Product Description

The aFe 51-76315 Momentum GT Cold Air Intake with Pro DRY S filter is a high-performance direct-fit intake system designed specifically for 2012-2016 BMW Z4 sDrive28i models equipped with the 2.0L turbocharged N20 engine. This Momentum GT system replaces the restrictive factory airbox with a sealed housing and dyno-tuned intake tube that dramatically increases airflow - up to approximately 90 % more than stock - allowing for better throttle response and engine breathing. The Pro DRY S synthetic air filter is oil-free, washable, and reusable, providing a balance of high airflow and reliable filtration without the need for oiling cycles, making maintenance easier over time.

Featuring a clear integrated sight window, you can quickly inspect the filter's condition without disassembly, saving time during routine checks. Premium hardware, including stainless-steel T-bolt clamps and silicone coupling, ensures a secure and durable installation that uses existing factory mounting points with no cutting or drilling required. With estimated gains of +7 HP and +10 lb-ft torque under ideal conditions and a significant airflow improvement over the stock intake, this intake provides a noticeable performance upgrade for Z4 owners. Note that this part is not currently CARB exempt and may not be legal for sale or use in California, New York, Maine, and other CARB states - always verify local emissions regulations before purchase.
