Product Description

The aFe Power 54-76307 Momentum GT Pro 5R Cold Air Intake System is a performance-engineered replacement air intake designed specifically for 2014-2018 BMW 328d and 328d xDrive models equipped with the 2.0L turbo diesel N47 engine. This Momentum GT system replaces the restrictive stock air box with a sealed one-piece housing and oversized Pro 5R radial flow air filter to maximize cool, dense air delivery into the engine. The integrated clear sight window allows for quick, tool-free inspection of the air filter, and the CAD-designed roto-molded intake tube improves throttle response and airflow throughout the rev range.

Engineered to outflow the factory unit by up to approximately ~53 %, the 54-76307 delivers dyno-proven gains of up to +15 HP and +28 lbs-ft of torque, helping to improve acceleration and efficiency. Installation is straightforward with a direct bolt-on design requiring no cutting or drilling, and the washable, reusable Pro 5R filter helps reduce long-term maintenance costs. Fitment confirmed through 2018; coverage beyond 2018 is unconfirmed at time of listing.
