The AEM 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. Included is a washable, reusable AEM Dryflow air filter. Made from an oil-free, synthetic filter media. This cone-shaped air filter can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). To help keep the radiant heat in the engine bay away from the air intake, a custom shaped heat shield with edge trim lining is included. The mandrel-bent aluminum air intake tube features an attractive, durable gunmetal gray powder coated finish for lasting good looks. The factory MAF sensor and PCV hose each mount on the tube. 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. View the vehicle applications to determine the legal status for each vehicle. AEM's Performance Cold Air Intake Systems are designed, tuned and dyno-tested to give your engine more power and acceleration by replacing the restrictive factory air filter, air intake tubing and air box assembly.
