Airflow efficiency and maximizing the potential of the stock intake design were the keys to development for the Dinan S65 intake. Dinan improves on the factory air box system by using a larger K&N filter combined with a precision molded carbon fiber intake tube. The increased amount of air feeds the engine and elicits a slightly more audible and sporty tone over its stock counterpart. Dinan claims 8hp and 5ft-lb torque gain with this kit.

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 E92/E93 335i Dinan intercooler is 93% larger than stock but is a direct replacement with only minor trimming of plastic undertrays required for installation. The factory charge piping in and out of the intercooler is re-used.
