The AEM 21-797C Cold Air Intake System produces torque and horsepower gains by replacing your vehicle's restrictive factory air intake housing and air filter.
Designed, tuned, and dyno-tested, this air intake system fits specific Volkswagen Jetta models.
The system allows air to enter through an oversized AEM Dryflow synthetic washable air filter for outstanding filtration, performance, and air flow.
The original air box space houses the air filter, which is protected by a heat shield designed to reduce intake air temperature and increase horsepower.
Constructed from mandrel-bent aluminum, the air intake tube features a durable gunmetal gray powder coated finish.
Developed to accommodate the engine's factory emissions control devices, including the breather 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.
Installation of the air intake system is easy 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.
