Testing vs the OE Civic Si Radiator hasn’t been conducted at this time. However, CSF did test the FL5 Civic Type R Radiator (CSF #7221) which uses the same core as the FE1 Civic Si Radiator (CSF #7222). The factory CTR radiator is more efficient than the factory Civic Si radiator so improvements with the CSF Radiator should be much more significant.
The test compared the FL5 CTR Factory Radiator to the CSF Radiator on an FL5 tuned to 294 whp and equipped with an upgraded/larger Front Mount Intercooler. The larger front mount intercooler has been shown to raise engine coolant temperatures by ~7%. This is due to the airflow restriction over the radiator. Test results showed a decrease of 8°C engine coolant temperature with the CSF Radiator vs OEM. As you can see, a radiator upgrade will be very important to anyone running a larger intercooler. The upgraded radiator will also be beneficial to anyone tracking their car.
