FE1 Civic Si / DE4 Integra High-Performance All-Aluminum Radiator

Out of the box, the FE1 Civic Si along with its Acura sister car, the DE4 Integra, are both very capable vehicles. Powered by Hondas 1.5L Turbo making 200hp, these small sedans have ample performance for those looking for a spicier daily driver. While the cars are capable of having some fun on the track and doing very spirited driving, hard track driving can quickly tax the limits of the factory equipment. This is especially true of modified and tuned examples where the engine is generating a lot more heat. That is why CSF is pleased to announce the new High-Performance All-Aluminum Radiator for the 2022+ FE1 Civic Si and DE4 Integra.

CSF has a long and successful track record with Honda cooling systems. This history includes making factory radiators for Honda Performance Development (HPD). Honda uses 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 for the new FL5 CTR and the FE1 Civic Si. Like the racing radiator, this new High-Performance version features CSFs 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.

The original OE radiator from Honda is a plastic tank with a single row aluminum core design. While this is generally accepted as good quality and durable, it is not the best option for high horsepower builds and hard driving. Turbo cars get hot, and the L15CA is no exception. Anything you can do to help keep temperatures in check will improve longevity of your motor and components.
