Product Description

The aFe 51-76307 Momentum GT Cold Air Intake with Pro DRY S filter is a premium diesel intake upgrade designed specifically for 2014-2018 BMW 328d and 328d xDrive models equipped with the 2.0L N47 turbo diesel engine. This direct-fit cold air intake replaces the factory airbox with a single-piece sealed housing and dyno-tuned intake tube to dramatically increase airflow - up to approximately 53 % over stock - resulting in enhanced torque delivery, throttle response, and overall engine breathing. The included Pro DRY S synthetic air filter is oil-free, washable, and reusable, providing both high performance and easy maintenance.

Featuring premium materials like reinforced silicone couplings and stainless steel T-bolt clamps, this intake installs securely using existing factory mounting points with no cutting or drilling required. The clear sight window integrated into the housing lets you quickly inspect the air filter condition without disassembly. With estimated gains of up to +15 HP and +28 lb-ft torque under optimal conditions and CARB 50-state legal compliance (EO# D-550-29) on many applications, this intake is a strong bolt-on upgrade for BMW diesel owners - always verify your local emissions regulations before purchase.
