Product Description

The aFe 51-76313 Momentum GT Cold Air Intake with Pro DRY S filter is a high-flow performance intake system designed specifically for BMW models equipped with the N55 3.0L turbocharged inline-six engine, including the 135i, 335i (and xDrive variants), and X1 xDrive35i spanning model years 2011-2015. This Momentum GT system replaces the restrictive factory airbox with a single sealed housing and CAD-tuned intake tube that increases airflow by up to approximately 16 %, improving throttle response, engine breathing, and overall driving feel. The oil-free Pro DRY S synthetic air filter is washable and reusable, offering excellent filtration and easy maintenance over time.

Featuring premium construction including a high-quality roto-molded housing, dyno-tuned intake tube, silicone coupling, and stainless steel T-bolt clamps, this intake system provides a secure, vibration-resistant installation using existing factory mounting points with no cutting or drilling required. Under ideal conditions, drivers can expect estimated gains of up to approximately +12 HP and +14 lb-ft of torque over the stock design. Note: this intake is not currently CARB exempt and may not be legal for sale or use in California and other CARB states - always verify your local emissions regulations before purchase.
