E90 and E92 328 Ram Air Intake System

Dinan's new Ram-Air Intake Assembly is now available for the E90/92 328 Sedans and Coupes!

The systems take full advantage of the ram air effect by literally scooping up additional cool air from the area next to the brake duct, supplementing the existing intake ducting for a better breathing 328. The result is increased horsepower and torque, as well as improved throttle response.

The system has been designed to work with the factory air box, fitted with the included free flow air filter element. A powder coated aluminum "air scoop" feeds greater volumes of cool air through a silicone hose and injection-molded air-box duct for a virtually invisible but highly effective performance upgrade.

The system produces a maximum gain of 7 hp and 6 lb-ft torque at 6600 rpm.
