2009 BMW 528i Performance Air Intake Kits

A high-density polyethylene (HDPE) rotationally-molded tube helps increase the volume of airflow to your engine, and provides a guaranteed increase in horsepower and torque. These systems are paired with a washable, reusable High-Flow Air Filter featuring oiled cotton filter media. The oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. A custom heat shield helps protect intake air from the high temperature of your engine bay, and the entire system can typically be installed in less than 60 minutes.

Easy to install one piece 16-gauge powder-coated heat shield requires no cutting or drilling. Stylish powder-coated steel or brushed aluminum cover blocks heat and directs cold air to the filter while quieting intake noise. The 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.

Maximum performance within minutes is what this aFe Stage 1 cold air intake system delivers. Enclosed in a durable 16 gauge heat shield; a massive washable/reusable; 360 deg. conical Pro 5R air filter increases airflow resulting in an additional 6 hp; and 7 lbs./ft/ torque. This intake system also features a unique 3-angle adaptor for increased air velocity. The Pro 5R air filter is constructed with 100 percent polyurethane for long life and multiple cleaning cycles. This intake is the easiest intake on the market to install. Simply remove the factory intake and mount the 3-angle adaptor with the air filter to the MAF sensor tube and you are breathing more air and producing more power.

Advanced Flow Engineering, Inc. (aFe) produces high flow, high performance air filters & intake systems for the automotive industry. Founded in April, 1999, aFe was created to address an obvious need in the automotive aftermarket industry: a lack of choice for a high performance aftermarket air filter. We are a team of engineers, machinists, production and sales people who believe in the product we design. We each have years of experience in our respective positions and together work to ensure that we have the best product on the market. Our purpose was not just to be another vendor that offers air filters, we chose to pay attention to those finer details that set an aFe filter apart from the competition. We currently offer aftermarket air filters for passenger cars, light trucks and SUVs. We also have many applications for round racing and universal clamp-on filters.
