E Chassis 5" HD Intercooler N54 N55 135 1M 335 X1 (Stepped core) MAD BMW

The stock BMW intercooler is small, inefficient, and cannot keep up with the high boost levels that tuned vehicles demand. The MAD BMW 5” Intercooler is engineered to keep intake air temperatures under control, allowing your BMW to perform at its best under all driving conditions.

Designed specifically for E-Chassis BMW N55 applications, the MAD 5” intercooler features a high fin density stepped core for maximum cooling efficiency and improved airflow. Measuring 21"x8.5"x5" and weighing only 22 lbs, it delivers the ideal cooling solution for Stage 1 setups while maintaining excellent fitment and responsiveness.

This intercooler is fully compatible with both stock and aftermarket charge pipes, making it a perfect upgrade for stock or tuned vehicles.
