# CSF FE1 Civic Si / DE4 Acura Integra High Performance All Aluminum Radiator

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 CSF's 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.
