On a VW Jetta 1.8T or VW Jetta GLI 2.0T, the stock air intake system channels air to the turbo through a series of narrow tubes with tight bends, and uneven surfaces. This tube design not only heats up the air, but it also causes power-robbing air turbulence, and it limits the volume of air ultimately going into the engine. The AEM 21-764C Performance Intake System reduces these airflow restrictions with a wider AEM aluminum intake tube that has mandrel-bent wide-angle bends, to straighten the airflow path and significantly reduce air turbulence. The high-volume intake tube also features a durable gray powder coat finish, and a built-in fitting for the factory PCV hose. Since this AEM Cold Air Intake was designed to be a direct replacement for the factory system, It won't require any under-hood modifications, and installation should only take around 90 minutes.
To send cold air to the VW turbo, an oversized AEM Dryflow air filter sits behind an aluminum heat shield, which is located where the factory airbox used to be. The top of this rugged heat shield has a special rubber gasket that seals against the underside of the hood, to prevent that big AEM air filter from ingesting warm air from the engine bay. The unique shape of the AEM heat shield was specifically engineered to channel cold air from outside the engine compartment, directly into the air filter. That steady supply of cold air then passes through the synthetic air filter, which is able to trap far more contaminants than an OEM paper air filter. And thanks its 3-dimensional synthetic material, dirt stays trapped inside a web of fibers, which means you won't have to clean it for up to 100,000 miles. Plus, the AEM Dryflow filter, along with the rest of this cold air intake system, is backed by AEM's Lifetime Limited Warranty.
