This system is the only one available 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: $65.00. 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.
