2006-2011 Honda Civic SI Koyo All Aluminum Radiator

All Aluminum Radiator (Racing)

With over 50 years of experience in the manufacturing of OE replacement radiators, it was only natural that we develop a lightweight, high performance radiator line. We are proud to offer our all aluminum performance radiators designed as a true drop in installation for select vehicles, utilizing the factory equipped fan shrouds without any modifications necessary.


V SERIES 36mm Core Thickness

Designed for applications where engine configuration/size cause clearances issues for thicker core radiators. In this case, the 36mm V-Core Series will suit your needs. Intended for both circuit and daily use. Unless noted otherwise, all Koyorad V-Series All Aluminum Radiators are Nocolok brazed, designed as a factory fit, direct bolt in with no engine modifications necessary, and retain mounts for the stock fan shrouds and fans. See notes in individual item descriptions for details.
