The adapter lowers intake air temps as coolant is no longer connected the intake manifold. Hondata has shown that intake air density will drop 1% for every 5°F increase in intake temperature. This is wasted power that can easily be gained back by using the adapter.   The adapter also features a 1\/8 NPT port for a coolant temp sensor commonly used in swap cars.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eThe Intake Manifold Adapter can be installed either using our spring loaded tab or by tapping the head. We use Honda Bond or similar gasket maker as it provides a strong seal and when using the spring loaded tab when the adapter isn’t under pressure there will be no chance of leak. The spring loaded tab holds the adapter down with constant spring pressure to ensure a tight fit and seal. The other option is using the provided blind hole you can easily tap the head for the second hole. Tapping the head will require a 6.5mm drill bit (to finish the blind hole in the adapter), 5mm drill bit (to drill the head), and M6x1.0 Tap. \u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eQuick Instructions:\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003eRequired Tools\u003c\/div\u003e\n\u003cdiv\u003eDrill\u003c\/div\u003e\n\u003cdiv\u003e1\/4 or 6.5mm drill bit\u003c\/div\u003e\n\u003cdiv\u003e13\/64 or 5mm drill bit\u003c\/div\u003e\n\u003cdiv\u003eM6x1.0 tap (Standard and bottoming)\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eBegin by using the 6.5mm or ¼ drill bit to finish the blind hole in the adapter. You then want to install the manifold and adapter on the head. This will ensure you are properly positioning the hole. Once you have marked where you want to drill remove the manifold and adapter. Place tape or plug the holes on the head for intake and coolant to prevent anything from getting inside.  You will use a 5mm or 13\/64 drill bit to drill the head to a depth of  at least 11mm (the depth of the bolt) but shouldn’t need more than 14mm. You can apply tape on the drill bit to ensure not to drill too deep. Once you drill the hole you will run your tap. Use a M6x1.0 tap and lube and do it slowly. Be careful not to tap too deep. You can start the thread with a standard tap but you should finish it using a bottoming tap. This will allow the bolt to use most of the tapped hole. Slowly start to tap the head and check fitment of your adapter often. You want the adapter to hold snug but not tap the hole to far. \u003c\/div\u003e","brand":"K-Tuned","offers":[{"title":"Default Title","offer_id":32376779735145,"sku":"KTD-K24-IM2","price":131.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0296\/2355\/0057\/products\/KTD_K24_IMA__32929.jpg?v=1589391085"},{"product_id":"heater-outlet-plug","title":"K-Tuned - Heater Outlet Plug","description":"\u003cmeta charset=\"utf-8\"\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eApplications:\u003c\/strong\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eK-series cylinder heads \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003eNote:\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e* Cylinder heads with heater hose fitting besides the header\u003c\/div\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e* The tread on the head is M20x1.0\u003c\/div\u003e\n\u003cp data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e\n\u003cp data-mce-fragment=\"1\"\u003eSome of you may be interested in deleting the heater hoses and heater core from your K-swapped vehicle.  The K-Tuned Heater outlet plug is made from zinc plated steel and allows removal of the OEM heater hose fitting found on the exhaust side on some K-series cylinder heads.  For installation, simply remove the OEM pipe fitting and replace it with our K-Tuned plug for a nice clean look.  The plug comes with a new crush washer to prevent any coolant leaks.  Ugly looped heater hoses are no longer needed.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"K-Tuned","offers":[{"title":"Default Title","offer_id":32376779767913,"sku":"KHP-PG-302","price":17.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0296\/2355\/0057\/products\/khp-pg-302__1.jpg?v=1599851846"},{"product_id":"swivel-neck-coolant-recirculation-fitting","title":"K-Tuned - Swivel Neck Coolant Recirculation Fitting","description":"If you have a street car with deleted heater hoses you can remove the entire OEM plastic T-stat housing and mount the K-Tuned Swivel Neck directly to your water pump passage for a cleaner and simpler look.  If you choose this setup you will need our K-Tuned recirculation fitting to allow coolant flow when the T-stat is closed.  It also helps prevent air pockets from forming in the cooling system during coolant bleeding.","brand":"K-Tuned","offers":[{"title":"Default Title","offer_id":32376779800681,"sku":"KST-CF-101","price":21.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0296\/2355\/0057\/products\/KST_CF_101__86176.png?v=1589391087"},{"product_id":"water-pump-mount-bracket","title":"K-Tuned - Water Pump Mount Bracket","description":"\u003cmeta charset=\"utf-8\"\u003e\u003cspan data-mce-fragment=\"1\"\u003eApplication: \u003c\/span\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eK-Tuned Water Pump and all K-Series Blocks Including K24Z Series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003eNote:\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e* This water pump mount fits our K-Tuned water pump as well as Meziere WP136S \u003c\/div\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e* May fit other water pumps as well\u003c\/div\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/div\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003eThe water pump mount bracket is a nice and simple way to mount your K-Tuned Water Pump on your K-Series block.

They’re proud to advertise their products as being equipped with ARP rod bolts. And for good reason. The “weak link” in a connecting rod has always been the bolt, and racers know that nobody builds a better bolt than ARP. However, it is critically important to monitor the stretch of each bolt and replace it when it has permanently elongated by .0005è. Below you will find an extensive listing of aftermarket connecting rods and replacement bolt specifications.   In some instances, you may want to go to an ARP rod bolt made from a better grade of material. This will provide you with improved reliability. However, please understand that when you want bolts made from exotic, super high strength materials, the cost will increase significantly. If you’re on a budget, it’s best to go with the most cost-effective solution. This is typically defined by the loads that are carried by the bolts in terms of piston\/rod weight and the rotational speed of the engine. The most cost effective design is the one in which the bolt strength is just great enough to handle its anticipated load – plus a safety margin for the occasional overloads. Using a material which has far more strength than required is not as cost effective – but will definitely give you an extra margin of safety and longer service life.   You should also know that ARP rod bolts are superior to those from other manufacturers. Especially in the area of fatigue strength. Testing has shown ARP rod bolts to have ten times the fatigue strength of other bolts. In the chart below, you’ll find a bar chart that graphically shows the difference between ARP Pro Series rod bolts and the fastener made by a leading competitor. It’s easy to see why ARP bolts are superior. As such, it makes good sense to rely on ARP for optimum connecting rod service and reliability. Make the most of your racing budget and rely on ARP rod bolts. You’ll find the ARP name proudly stamped on each bolt as your assurance of quality.   *Features*  * Forged in-house at ARP using only the finest quality materials  * Heat-treated using special vertical racks to assure complete 360° penetration  * Threads rolled after heat-treat to provide up to 10-times longer fatigue strength  * Precision CNC-machined to exacting specifications  * Specially designed for optimum reliability in each application   *Wave-Loc Features*  * Wave-Loc surface contacts the rod and cap for optimum alignment and reduction of fluctuating stress – which strengthens the rod itself!  * Provides snug fit for all OEM connecting rods (interference range of .001è to .005è), despite wide range of factory rod bolt hole tolerances.  * Available for most applications.  * Superior material grain flow because of patented Wave-Loc surface design as compared to knurled bolts that have sharp edges and “built-in” stress risers.  * Galling and scoring of the rod is virtually eliminated because there is only smooth contact and absolutely no “digging.”   *Materials Used In ARP Connecting Rod Bolts* *8740 CHROME MOLY:* Until the development of today’s modern alloys, chrome moly was popularly considered a high strength material. Now viewed as only moderate strength, 8740 chrome moly is seen as a good tough steel, with adequate fatigue properties for most racing applications, but only if the threads are rolled after heat-treatment, as is the standard ARP production practice. Typically, chrome moly is classified as a quench and temper steel, that can be heat-treated to deliver tensile strengths between 180,000 and 210,000 psi.   *AERMET:* With a typical tensile strength of 290,000-310,000 psi, Aermet is a new martensitic super-alloy that is stronger and less expensive than the super-alloy austenitic materials that follow. Because it is capable of achieving incredibly high clamping loads, it is ideal for short but extreme environments like top fuel, funny car and some short track applications. Although Aermet is a maraging steel that is far superior to other high strength steels in its resistance to stress corrosion, it must be kept well-oiled and not exposed to moisture.   *ARP2000:* ARP2000 is an alloy steel that can be safely heat treated to a higher level, producing a greater strength material than 8740. While 8740 and ARP2000 share similar characteristics – ARP2000 is capable of achieving a clamp load at 220,000 psi. ARP2000 is used widely in short track and drag racing as an up-grade from 8740 chrome moly in both steel and aluminum rods. Stress corrosion and hydrogen embrittlement are typically not a problem, providing care is taken during installation.   *L19:* This is a premium steel that is processed to deliver superior strength and fatigue properties. L19 is a very high strength material compared to 8740 and ARP2000 and is capable of delivering a clamp load at 260,000 psi. It is primarily used in short track and drag racing applications where inertia loads exceed the clamping capability of ARP2000. Like most high strength, quench and temper steels – L19 requires special care during manufacturing to avoid hydrogen embrittlement. This material is easily contaminated and subject to stress corrosion. It must be kept well-oiled and not exposed to moisture.   *INCONEL 718:* A nickel based material that is in the high temperature, super-alloy class, it is found to be equally suitable in lower temperature applications. This material delivers tensile strengths in the 210,000-230,000 psi range and exhibits improved fatigue properties. Best of all, Inconel 718 is completely immune to hydrogen embrittlement and corrosion.   *ARP3.5 (AMS5844):* While similar to Inconel 718, these superalloys are found in many jet engine and aerospace applications where heat and stress attack the life of critical components. The high cobalt content of this alloy, while expensive, delivers a material with superior fatigue characteristics and typically tensile strength in the 260,000-280,000 psi range. The immunity to hydrogen embrittlement and corrosion of these materials is a significant design consideration. These materials are primarily used in connecting rods where extremely high loads, high RPM and endurance are important factors – Formula 1, NASCAR and IRL applications.   *CUSTOM AGE 625 PLUS:* This newly formulated super-alloy demonstrates superior fatigue cycle life, tensile strength and toughness – with complete resistance to atmospheric corrosion and oxidation. ARP is the first to develop manufacturing and testing processes for fasteners with Custom Age 625+. Best of all it is less expensive and expected to soon replace MP-35 as the material of choice in the high strength, super-alloy field. Typical tensile strength is 260,000-280,000 psi.","brand":"ARP","offers":[{"title":"Default Title","offer_id":32376782454889,"sku":"200-6207","price":79.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0296\/2355\/0057\/products\/200_6207__00419.jpg?v=1589391118"},{"product_id":"arp-nissan-head-stud-kit-rb25","title":"ARP - Nissan RB20\/20DET RB25\/25DET Head Stud Kit","description":"It is for good reason that virtually every top professional engine builder relies on ARP Pro Series head studs for their all-out competition powerplants. Simply stated, there’s not a better stud setup on the market today.   For openers, ARP uses a premium grade 8740 alloy that is rated far superior to “aircraft” quality. Each stud is placed vertically in special racks and precisely heat-treated to 200,000 psi. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers who just dump pieces in a basket and hope for the best.   Following heat-treat, each stud is centerless ground to make it as close to perfectly concentric as possible. This procedure involves about ten very slight cuts and results in an exceptionally straight part. It’s important to note that lesser quality studs are not even centerless ground – the material is thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). Because ARP studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned – something that won’t happen with inferior quality head studs.   ARP studs are thread rolled after heat-treat, which gives them about 1000% (that’s ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice). It costs a lot more to do it this way, because it’s tough on tooling, but the results are well worth the extra effort.   You will also note that ARP offers specially undercut studs for several engines. This procedure (done only to the shorter studs) more equalizes the “stretch” of both studs, which makes for a more consistent clamping force – and one that compensates for head gasket compression when the cylinder heads are installed. This helps prevent blown head gaskets, and assures optimum engine sealing!   Premium quality heat-treated 8740 chrome moly steel head stud kits are available for most every domestic and import applications.   You won’t find a better quality stud on the market from any other source. Look for ARP stamped on each stud as your assurance of quality.   Clearly, ARP Head Stud\/Bolt Kits are the best on the market today, and the favorite of leading professional engine builders in all forms of racing.   *HIGH PERFORMANCE SERIES* High Performance head bolts are available with a reduced wrenching hex or 12-point and wide area flanged head that eliminates the need for valve train removal to facilitate cylinder head retorquing. All High Performance Series bolts are 180,000 psi (which is 15% stronger than Grade 8) and kits come complete with hardened parallel-ground washers.   *PRO SERIES* All Pro Series bolts are cold-forged to ensure molecular integrity, heat-treated prior to thread rolling and machining, and are rated nominally at 200,000 psi. ARP Pro Series head bolt kits are application specific – designed for use with typically competition only components. These fasteners deliver superior strength and meet the ARP “ZERO defect – ZERO failure” quality standard. Hardened and parallel-ground washers are included with each kit to ensure even load distribution and accurate torque readings. All Pro Series head bolts have a reduced wrenching hex or 12-point head and wide area flange to eliminate the need for valve train removal for cylinder head retorquing and permits the use of larger diameter valve springs. Most applications have undercut short bolts that can help eliminate head gasket failures through providing more “stretch” to compensate for the additional compression of gaskets.     *Head Studs vs Bolts* On many street-driven vehicles, where master cylinders and other items protrude into the engine compartment, it’s probably necessary to use head bolts so that the cylinder heads can be removed with the engine in the car.    For most applications, however, studs are recommended. And for good reason. Using studs will make it much easier to assemble an engine (especially a racing powerplant which must be serviced frequently and quickly!) with the cylinder head and gasket assured of proper alignment.    Studs also provide more accurate and consistent torque loading. Here’s why. When you use bolts to secure the head, the fastener is actually being “twisted” while it’s being torqued to the proper reading. Accordingly, the bolt is reacting to two different forces simultaneously. A stud should be installed in a “relaxed” mode – never crank it in tightly using a jammed nut.   If everything is right, the stud should be installed finger tight. Then, when applying torque to the nut, the stud will stretch only on the vertical axis. Remember, an undercut shorter stud will have a rate similar to a longer, standard shank stud. This provides a more even clamping force on the head. Because the head gasket will compress upon initial torquing, make sure studs and bolts are re-torqued after the engine has been run.","brand":"ARP","offers":[{"title":"Default Title","offer_id":32376782520425,"sku":"202-4301","price":190.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0296\/2355\/0057\/products\/202_4301__47636.jpg?v=1589391113"},{"product_id":"arp-nissan-head-stud-kit-ka24de","title":"ARP - Nissan 2.4L KA24DE 12pt.

The most cost effective design is the one in which the bolt strength is just great enough to handle its anticipated load – plus a safety margin for the occasional overloads.
