2011 BMW 328i Performance Air Intake Kits

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

Product Features:

• Uses Pro 5R Air Filter For Maximum Air Flow
• Rotomolded Plastic Tube
• 56% cfm Flow Gain
• Improved Throttle Response

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

Sealed, molded plastic or aluminum cover provides factory style with less intake noise than open systems. Our specially engineered air box openings pull cold air from outside the engine compartment increasing engine efficiency and producing greater performance gain. The cross-linked polypropylene rotomolded plastic air box replaces restrictive stock air box and ensures a consistent supply of cold fresh air; built-in ram scoop forces cold, outside air to filter. Precision designed molded plastic intake tube maximizes airflow volume and speed for optimum power gains. 360 degree flow, washable and reusable, limited lifetime filters are high flow and high performance.

Product Features:

• Uses Pro DRY S Air Filter For Maximum Convenience
• Rotomolded Plastic Tube For Maximum Air Flow
• 48% cfm Flow Gain
• Improved Throttle Response

This Performance Air Intake System allows your engine to breathe more air compared to the restrictive factory air intake housing. It is designed, tuned And dyno-tested to produce more horsepower And torque. Air enters the system from the factory fresh air inlets. through replacement air duct And into a roto-molded, aerodynamic AEM air box containing an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration And performance.The cone shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). This Air Intake System is backed by AEM’s Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California And other states adopting California emission standards, while others are 50 state legal.
