AEM Brute Force HD air intakes are specifically designed for large-displacement engines and are dyno-tested to deliver more torque and horsepower than every other intake system on the market. They're constructed from CNC mandrel-bent 6061 aluminum and feature reinforced TIG-welded brackets and fittings for maximum durability. Each system is tuned to be application-specific and deliver maximum torque and horsepower at every throttle position. For superior filtration, AEM utilizes an extra-large, proprietary, 4-layer cotton gauze element that reduces restriction without compromising filtering capability. AEM also includes a heavy-duty stainless steel heat shield, a complete hardware kit, and installation instructions.
