CAD designed by experienced engineers and CNC cut and formed, the Kinematic Speed E36 Radiator duct has been tested in the harshest track conditions on hot Southeast race tracks in the peaks of summer on E36s with S50, S52, and even S54 powerplants, with substantial increases in cooling efficiency and the durability to handle the rigors of track duty with outstanding results, all with the ease of bolt-on installation using existing attachment points. No cutting or drilling required.
Great for endurance racers, sprint racers, track day enthusiasts, and anyone looking for the most bang for the buck in cooling system improvements on the E36 platform. The Kinematic Speed E36 duct is designed to work with OEM or OEM-style replacement radiators without AC installed. Oversized radiators, oil coolers, or other modifications within the space between the OE radiator and bumper may require modification of the duct for clearance. $199.99.
