This Performance Air Intake System allows your engine to breath more air compared to the restrictive factory air intake housing. It is designed, tuned, and dyno-tested to produce more horsepower and torque. 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). A custom shaped heat shield with edge trim lining is included to keep engine bay heat from the air intake. The air intake tube is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish.
