Upgrade from your stock intercooler to the MAD stepped core intercooler for maximum performance and reliability!

The stock BMW intercooler is small, inefficient, and cannot keep up with the high boost that your tuned car targets. MAD BMW 5” intercooler will keep the intake air temperature in check, allowing your BMW to perform at its best at all times.   

The MAD F chassis BMW 5” intercooler uses a high fin density core for maximum cooling. It also features a stepped core design to maximize the cooling area. Weighing 22lbs only with dimensions of 21"x8.5"x5", It provides the perfect cooling solution for stage 1 applications.  

This intercooler is compatible with stock and aftermarket charge pipes.
