Product Details

The Civic Type R has long been regarded as one of the best bang for the buck performance vehicles on the market, and the new FL5 Civic Type R (CTR) is no exception. While some may gripe about its FWD configuration, there is no denying it is an absolute beast on and off the track. The CTR twin, the Acura Integra Type S shares most of the key components and is equally as capable.

While out of the box, the FL5 CTR is an incredibly well engineered vehicle, it still has its shortcomings. The factory cooling system is more than capable of keeping up with spirited driving and a daily commute. However, it starts to show its limitations when pushed hard on the track or when tuning is involved. From a quick flash tune to full big turbo builds, better cooling will always be beneficial. That is why CSF is pleased to announce the new High-Performance All-Aluminum Radiator for the 2023+ FL5 Civic Type R and DE5 Integra Type S.

CSF has a long and successful track record with Honda cooling systems. This history includes making factory radiators for Honda Performance Development (HPD). Honda utilized the CSF private label HPD Race Radiator for the FK8 Civic Type R TCR and recently took delivery of a new system CSF developed for the FL5. CSF used the information and experience from building this Race Radiator to design a High-Performance version that would be available to the masses. Like the racing radiator, this new High-Performance version features CSF latest 5mm fin cooling technology. The new fin design increases the heat transfer area of the radiator by 20-25% over other larger fin designs.
