The CSF 8343 is a dual engine oil-cooler system for the FL5 Civic Type R and listed DE5 Integra Type S application. Two dual-pass bar-and-plate coolers mount at the bumper sides and operate in series.
A thermostatic billet sandwich plate starts opening at 175°F / 80°C and is fully open at 195°F / 90°C. Motorsport oil lines use DYME quick-release fittings. Carbon bumper inlet vents, fender-liner louvers and a replacement washer bottle address packaging and airflow around the side-mounted coolers.

Product FAQs
Is the DE5 installation identical to the FL5?
No. The included CSF bumper vents are not designed for the DE5 bumper inserts. The Integra installation requires its own insert modifications and airflow solution.
Does this kit require body or duct modifications?
Yes. The FL5 installation includes cutting of the bumper, fender liners and brake ducts, plus rivet-nut installation in the crash-beam rails.
When does the oil thermostat open?
It starts opening at 175°F / 80°C and reaches full opening at 195°F / 90°C, rather than bypassing oil cooling only at one fixed temperature.
