The CSF 8266 replaces the factory unit with a high-performance design engineered to handle the thermal loads of vehicles pushing over 800 horsepower. This cooler utilizes CSF AC Condenser Technology, featuring a 1-row super-high pressure 32mm 10-channel microtube to provide optimal oil flow and maximum surface area contact within the factory footprint.
