Show original supplier description
The stock BMW intercooler is often undersized and inefficient, especially in tuned vehicles targeting higher boost levels. The MAD 5" Stepped Core Intercooler directly addresses this by significantly improving intake air temperature management. This upgrade allows your BMW to maintain optimal performance consistently, even under demanding conditions. This intercooler features a high fin density core for maximum heat dissipation and a unique stepped core design that enlarges the cooling surface area. With dimensions of 21"x8.5"x5" and a weight of 22lbs, it is engineered for an OE fit, meaning no cutting is required for installation. It is compatible with both stock and aftermarket charge pipes. Mastery of Art and Design (MAD) specializes in bolt-on upgrades for forced induction BMWs, and this intercooler is presented as the best value in its category. The product is backed by a lifetime warranty covering defects and fitment, with a 90-day return period for unused items. This intercooler is designed to fit various BMW E82, E88, E90, E92, and E93 models equipped with N54 or N55 3.0L engines, including the 1 M Coupe, 135i, 335i, and 335xi submodels. Always verify fitment using the vehicle selector.
