3.0” modular intake kit for FWD 2.0L FSI equipped VW Golf/Jetta/GTI/Audi A3, 304 stainless tubing mandrel bent and electro-polished. 3.0” special CNC machined MAF housing with extensive flow optimization. Billet MAF mounting base and stainless bolts. This system is the only one available for the 2.0L FSI that has been engineerd to use a full 3.0” flow path (for max HP and torque) and will still work properly with any “chipped” or “reflashed” ECU on the vehicle. The kit also utilizes a strategically placed open element filter that is both high flowing and efficient in capturing cold air from the stock air ducting. The kit also comes with a aftermarket diverter valve reroute port for seamless future install of a stronger and more efficient aftermarket diverter valve using this mounting kit sold separately: ATP-VVW-173 . This mod should be an add-on to any “reflashed’ vehicle that has also been enhanced with an upgraded downpipe. This intake kit will unleash the 2.0FSI engines breathing ability even further and allows the engine to make power to redline without choking up. It replaces the entire stock intake elbow, filter, and airbox assembly including the stock restrictive MAF housing. It’s incredibly easy to install and all parts are supplied. It is also 100% compatible with our upcoming Garrett based turbo upgrade kit and components which are designed to support airflow requirements in excess of 450HP.
