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. 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.

The service was fantastic, I received a courtesy call the day after I placed my order. The intake was delivered ahead of schedule. The product itself is phenomenal, sounds fantastic looks great. Installation was tight due to the fitment of the tube. My only and very minor complaint would be, it would be convenient if AEM would supply a short section of hose and a hose barb to extend the factory vacuum line to the hose mender.

The quality of the air intake is great and fits perfectly. There is definitely a noticeable change in sound and it’s fantastic. As for HP gain I'm not eactly sure however it does feel a little peppier. The instructions are easy to follow with pictures. My only thing is I wish the rubber pieces to go on the side of the heat shield came pre cut. It was not a big problem however it would have saved 5 mins. I would definitely recommend buying if you are in the market for a fantastic air intake. At first I got a another intake but returned it after some Fitment problems. If you are looking at another intakes and deciding if you should go AEM or another brand I would go for AEM.

Great and finish was excellent..this CAI adds to the driving experience as the factory box and intake tube has restrictor baffles and a silencer tube. GREAT Bolt on
