Dinan Performance Intercooler for BMW | E9X | N54 (Std. Bumper) | D330-0009B
When modifying the car and increasing boost, installing an upgraded intercooler is essential to keep the engine computer from restraining boost as temperatures climb. The stock air-air intercooler is quickly overcome with heat and can't keep the intake air cool enough. If it's too hot the engine computer will reduce power to safer levels. A Dinan intercooler is much larger than stock, providing more surface area for cooling air to pass through. Even heat soak at low speeds is reduced, making this a worthwhile addition even for stock or mildly tuned engines. The E9X 335i Dinan intercooler is 93% larger than stock but is a direct replacement with only minor trimming of plastic under trays required for installation. The factory charge piping in and out of the intercooler is re-used.
Note: Does not fit vehicles equipped with Active Cruise Control. Does not fit M-Technic bumper.
