This Stage-2 Sealed Intake produces 12 hp and 15 lbs. x ft. torque and outflows the factory intake by 56%. Fully enclosed in a heat-shielding molded plastic housing; this air intake system features a washable/reusable conical air filter that improves airflow for increased horsepower and torque. The housing features auxiliary inlet duct for better airflow as well as an attractive black vacuum formed plastic cover that provides ready access to the filter for servicing. This intake system also features a heat-insulating molded plastic tube that replaces the stock intake tract and directs increased air flow with improved volumetric efficiency for maximum performance. The filter is constructed with 100% polyurethane for long life and multiple cleaning cycles.

Vacuum Formed ABS Cover:
This intake is topped with a vacuum formed ABS black cover that seals out hot intake air and provides an aggressive yet elegant look to your 3-series.
