Wagner Front & Side Heat Exchanger Kit - F8X M2/M3/M4
Drop-in upgrade for both main and auxiliary heat exchangers
Cooling for the top-mount charge air cooler is done with a pair of radiators in the nose of M2/M3/M4 with the S55 engine. A main radiator in front of the engine radiator and an auxiliary radiator in the right side of the bumper. These feed coolant to the top mount intercooler. By improving the cooling of the charged intake air, you can lower intake air temp and improve horsepower.
The Wagner aluminum radiators have much greater internal volume than stock - +89% for the front radiator and +94% for the side radiator. This is more capacity for coolant and less heat soak for the coolant circulating the system. The side radiator includes a new carbon fiber shroud for improved flow characteristics.
Each radiator is a plug-and-play install. The entire radiator is aluminum, even the end tanks, and coated for corrosion protection. All of the factory hoses and mounts are re-used and no modification is needed. All connections are CNC machined and TIG welded.
