The CSF High-Performance Dual Engine Oil Cooler Kit adds serious oil-cooling capacity to the 2023-2026 Honda Civic Type R FL5. It mounts two CSF #8119 dual-pass bar-and-plate coolers in the bumper sides with a purpose-built ducting and carbon-fiber vent system to feed airflow where the FL5 lacks it. The kit includes a billet sandwich plate with a 175-195F (80-90C) thermostat plus a 1/8 NPT oil-temp sensor port, motorsport AN lines with DYME PSI quick-release fittings, and increases oil capacity by over 2 quarts.
