BMW E46 M3 S54 (01-06) Mishimoto cooling Essentials bundle

The Mishimoto cooling bundle E46 renews the cooling system of the BMW E46 M3 with S54 engine from 2001 to 2006 in one go. Mishimoto bundles the parts that cause the most problems on the E46 M3: the radiator, the coolant hoses and the mechanical fan.

The S54 is a high-revving six-cylinder that produces a lot of heat on track. With a larger aluminium radiator, silicone hoses and an electric fan with its own controller you get more cooling capacity and full control of temperatures. According to Mishimoto, removing the mechanical fan gave up to 5 whp at high rpm in testing.
