Acuity - High-Temp Silicone Radiator Hoses for the  '12-'15 Civic Si

  • Silicone construction withstands temperatures up to 100F higher than OEM hoses
  • Black exterior with ACUITY purple hose lining
  • Upper hose design provides extra clearance for use with OEM or RBC-style intake manifolds
  • Includes upper radiator hose, lower radiator hose, and (4) German-style hose clamps

The High-Temp Solution to Tired, Old, Radiator Hoses:

The 9th Gen Civic Si's OEM radiator hoses are made from EPDM rubber. Unfortunately, in performance applications where coolant and under hood temperatures consistently higher than in normal driving conditions, EPDM degrades more quickly. Silicone is able to withstand temperatures over 100F higher than EPDM for sustained periods without losing strength or pressure holding ability. The upper hose features a unique design that provides additional clearance for use with an RBC or similar intake manifold where the throttle body is relocated and can interfere with the OEM upper radiator hose. These hoses feature 5mm walls with 4-ply polyester reinforcement. Hoses are SAE20R4# compliant.
