Description

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.

Customer Reviews (4.6 / 5 · 5 reviews)

Riley ★★★★★

The purple inner lining is a nice touch—makes the engine bay pop without being obnoxious. Took about 45 minutes to swap out the old hoses and everything sealed perfectly. Feels like a solid upgrade over the stock rubber.

Steven S. ★★★★★

Fit was spot on for my 2013 Si—the upper hose's extra clearance made installing it with my aftermarket radiator a breeze. The silicone feels much more durable than the factory rubber, and that purple lining is a nice surprise when you pop the hood.

Ruby G. ★★★★★

Swapped these on before a track day and the upper hose cleared my intake without any trimming, which was my main worry. The silicone feels way thicker than the stock rubber ones and the purple lining is a nice touch you only see up close. Held up fine through a full session of hard driving.
