Airflow efficiency and maximizing the potential of the stock intake design were the keys to development for the Dinan N55 intake. Dinan improves on the factory air box system by delivering more cool, dense air. The increased amount of air feeds into dual larger volume airbox complete with a larger cone filter that elicit a slightly more audible and sporty tone over its stock counterpart. Dinan claims 10hp and 15ft-lb torque gain with this kit.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. This intake is worth 3 points toward your Dinan badge.
