CSF Dual Oil Cooler Kit | 23+ Civic Type R FL5

Fits:

• 2023+ Honda Civic Type R (Hatch FL5)

_______

Drivers regularly see high oil temperatures on a completely stock FL5, and even higher on modified examples. In testing, CSF observed temperatures over 275°F (135°C) on track — it was clear the FL5 needed a real solution. That's what pushed CSF's engineering team to develop their first ever complete engine oil cooler kit, and the results speak for themselves: stunning performance with an aggressive look to match.

CSF spent over a year testing and developing this kit with R&D partners and drivers competing in Global Time Attack (GTA) and GridLife. Initial testing happened in the controlled environment of a dyno, then moved into aggressive real-world development on track — where most customers will actually be using these kits. Pair it with the CSF FL5 Performance Radiator for maximum cooling performance.
