2009 BMW 328i xDrive Engine Cold Air Intakes

The aFe Stage 2 cold air intake system produces up to 10HP and 12lbs. x ft. torque while outflowing the factory intake by up to 20. This intake includes a highly engineered heatshielded housing with a one-piece intake tube. Handling filter duties is the five layered, progressively finer mesh cotton gauze, oiled Pro 5R washable/reusable, 360 degree inverted top radial flow air filter that provides maximum filtration and high flow. The polished aluminum intake tube is engineered for improved volumetric efficiency and maximum performance while lowering Intake Air Temps (I.A.T). Utilizing factory mounting points, this system provides a hassle free installation.

Product Features:

• Uses Pro DRY S Air Filter For Maximum Air Flow
• Rotomolded Plastic Tube
• 56% cfm Flow Gain
• Improved Throttle Response

This Stage 2 Sealed Intake produces 12HP, 15LBS. x FT. of torque and outflows the factory intake by 56. This sealed air intake system features a washable/reusable 6 inch conical air filter with inverted top that improves airflow for increased horsepower, torque and throttle response. The air filter is constructed with 100 polyurethane for long life and multiple cleaning cycles. The sealed housing features two auxiliary air inlet ducts for increased airflow. To finish off your underhood appearance, an attractive vacuum formed ABS plastic cover with carbon fiber finish is used to provide easy access to the filter for servicing and an aggressive look. To complete this system, a dyno tuned molded plastic intake tube with velocity stack adapter replaces the stock intake tract and directs air flow with improved volumetric efficiency for maximum intake velocity
