The CSF 8343 is a complete high-performance dual engine oil cooler kit for the 2023-2026 Honda Civic Type R (FL5) and the 2024-2026 Acura Integra Type S (DE5), both running the turbocharged 2.0L K20C1. It pairs two CSF 8119 dual-pass oil coolers, each a 13 by 4.5 inch bar-and-plate core with an Aero-Flow bar design, TIG-welded cast end tanks, and 120 psi pressure testing. A billet aluminum sandwich plate with an integrated thermostat opens at 175F and is fully open at 195F, includes an M20x1.5 factory-filter adapter and a plugged 1/8 NPT port for a temperature sensor. The kit adds CPE-lined stainless braided lines with DYME Pro/Spec quick-release fittings, pre-preg carbon-fiber bumper vents, laser-cut fender-liner vents, a replacement washer reservoir, brackets, and templates. It raises total oil capacity to about 7 quarts and drops oil temperatures roughly 15F on the street and 17 to 30F on track. Installation requires trimming the front bumper, fender liners, and brake ducts. The supplied carbon bumper vents are designed for the FL5; DE5 Integra Type S installs require different bumper venting.
