Product Description
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.
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.
Just like the HPD Race Radiator, the CSF FE1 Civic Si / DE4 Integra Radiator features the latest 5mm fin technology. The smaller fins significantly increase the heat exchange surface area improving overall cooling efficiency. A 33% larger 2-Row 42mm aluminum core increases the fluid capacity of the radiator, and improves the cores ability to dissipate heat. CSF's Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance.
The TIG-Welded 100% All Aluminum construction increases the overall strength of the radiator. This improves durability and longevity so you can be confident it will hold up to hard driving conditions. The CSF radiator mounts in the factory location and requires no modifications or cutting.
