The AEM 21-764C Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle’s restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Volkswagen Jetta, Jetta GLI, and Passat models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is located in the original air box location and is protected by a heat shield which is designed to reduce intake air temperature and increase horsepower. The air intake tube is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. This air intake system was developed to accommodate the engine’s factory emissions control devices including the PCV hose. The tapered cylinder 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). The air intake system is easy to install with commonly available tools and it 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.

Hello, Over all I have been very satisfied with the product. I do have one issue with the intake, which is the welding job at the I believe crank case connection, the connection that is close to where the intake connects to the turbo. The weld job on one half is raised which limits the clearance that the factory piece has to snap into place. The connection isn't able to snap into place because of the welding job. The factory piece from the OEM intake is approximately three inches in length, which allows way more than enough room for the factory piece to connect to the intake, which snaps on and fits very securely into place. I believe the required amount of space is between one half to one inch, and the weld job restricts this by probably a millimeter or two. If the weld job had not been restrictive, I do believe it would have snapped into place and would have sat flush to the intake if the welding had not been in the way. The connection hasn't popped off, but I do feel it has not snapped into place where it belongs. Perhaps you could extend this welded piece on your intake by a centimeter, which would allow a perfect fit with a little extra room and a safety net with varying welding jobs. I am very happy with the induction noise created with the addition of the intake, and think that the instructions although brief, were very helpful. If the welding job had not had been restrictive, I would have rated this 5/5.

Excellent product. Quality made, and great detailed instructions. You can hear the turbo and feel it spool up quicker.
