Using our kit, you are able to completely remove the pressure-relief valve and replace it with a billet aluminum plate. This allows the factory breather system to function properly while eliminating the failure-prone relief valve. With the hose between the valve cover and intake manifold completely eliminated, the included boost cap is used to block off the hose connection on the end of the intake manifold. Our billet cap features a tapped hole that can be plugged or used to plumb a boost gauge, compared to competitor€™s products that do not offer a provision for plumbing a boost gauge. Features: Save your engine from a faulty pressure relief valve Direct replacement & quick installation IE boost cap has an optional outlet for a boost gauge Bright black anodized finish In-house CNC machined aluminum What's Included: Integrated Engineering PCV Solution Kit For 2.0T FSI Engines Fitment Details Audi - A4 2005-2008 (B7) 2.0T FSI (EA113) engines Audi - A6 2005-2011 (C6) 2.0T FSI (EA113) engines Audi - A6 Allroad 2005-2011 (C6) 2.0T FSI (EA113) engines Audi - TT 2008-2015 (MK2 - 8J) 2.0T FSI (EA113) engines* Audi - TTS 2008-2015 (MK2 - 8J) 2.0T FSI (EA113) engines Audi - A3 2006-2013 (MK2 - 8P) 2.0T FSI (EA113) engines* Audi - S3 2006-2013 (MK2 - 8P) 2.0T FSI (EA113) engines VW - GTI 2006-2009 (MK5) 2.0T FSI (EA113) engines* VW - Golf R 2012-2012 (MK6) 2.0T FSI (EA113) engines VW - Jetta & Jetta GLI 2006-2010 (MK5) 2.0T FSI (EA113) engines* VW - Passat 2006-2010 (B6) 2.0T FSI (EA113) engines* VW - EOS 2006-2015 (1F7) 2.0T FSI (EA113) engines* *NOTE: IE PCV Solution Kits only work on early model 2.0T EA113 engines. You can verify you have the correct engine if it is in the above chassis and is driven by a timing belt. If your engine is driven by a timing chain, you have an EA888 Gen1/Gen2 TSI engine and is not compatible with this product.
