# APR Audi/Porsche/Volkswagen R1 Diverter Valve The APR R1 Diverter Valve is a critical performance upgrade recommended at all stages of performance as it replaces the failure prone factory unit. The R1 is designed to withstand extreme boost pressures at the highest levels of performance, while offering lightning fast response thanks to the unit's friction-free diaphragm-based design. Unlike piston based units that can stick and bind in the winter, the APR R1 is virtually maintenance free, requiring no greasing or o-ring replacements, as is common with other units. Constructed from CNC-machined billet-aluminum with a high-temperature Nomex-reinforced diaphragm, the R1 is designed to be the last DV upgrade the engine will ever need! - Premium friction-free diaphragm-based design - No sticking or binding like pistons - Fits 1 inch inlet and outlet hoses - No maintenance like pistons - Nomex-reinforced diaphragm - Billet construction - Direct replacement This Part Fits: Year Make Model Submodel 1997-2005 Audi A4 Base 2003-2006 Audi A4 Cabriolet 1999-2005 Audi A4 Quattro Avant 1997-2005 Audi A4 Quattro Base 2000-2004 Audi A6 Quattro Base 2001-2005 Audi Allroad Quattro Base 2003 Audi RS6 Base 2001-2002 Audi S4 Avant 2000-2002 Audi S4 Base 2000-2006 Audi TT Base 2002 Audi TT Quattro ALMS Edition 2000-2006 Audi TT Quattro Base 2017-2025 Porsche 718 Boxster Base 2018-2019 Porsche 718 Boxster GTS 2017-2025 Porsche 718 Boxster S 2024-2025 Porsche 718 Boxster Style Edition 2020-2023 Porsche 718 Boxster T 2017-2025 Porsche 718 Cayman Base 2018-2019 Porsche 718 Cayman GTS 2017-2025 Porsche 718 Cayman S 2024-2025 Porsche 718 Cayman Style Edition 2020-2023 Porsche 718 Cayman T 2004 Porsche 911 40th Anniversary Edition 2014 Porsche 911 50th Anniversary Edition 1996-1997,2002-2005,2007-2009,2017-2019 Porsche 911 Carrera 1993-1994 Porsche 911 Carrera 2 1993-1994,1996-1997,2002-2004,2007-2009,2017-2019 Porsche 911 Carrera 4 2012,2015-2016,2018-2019 Porsche 911 Carrera 4 GTS 1996-1997,2002-2005,2010-2019 Porsche 911 Carrera 4S 2011-2012,2015-2016,2018-2019 Porsche 911 Carrera GTS 2010-2019 Porsche 911 Carrera S 2018-2019 Porsche 911 Carrera T 2002-2005,2008-2009 Porsche 911 GT2 2018-2019 Porsche 911 GT2 RS 2004-2005,2007-2008,2010-2011,2014-2016 Porsche 911 GT3 2007-2008,2010-2011 Porsche 911 GT3 RS 1993-1994 Porsche 911 RS America 1978-1983 Porsche 911 SC 1994,2011 Porsche 911 Speedster 1996-1997,2002 Porsche 911 Targa 2007-2009,2017-2019 Porsche 911 Targa 4 2016,2018-2019 Porsche 911 Targa 4 GTS 2010-2012,2014-2019 Porsche 911 Targa 4S 1991-1992,1996-1997,2001-2005,2007-2019 Porsche 911 Turbo 1993-1994 Porsche 911 Turbo 3.6 1976-1977,1986-1989 Porsche 911 Turbo Carrera 2005,2011-2019 Porsche 911 Turbo S 2018 Porsche 911 Turbo S Exclusive Series 1977-1982 Porsche 924 Base 1979-1982 Porsche 924 Turbo 1978-1979 Porsche 930 Turbo 1983-1989 Porsche 944 Base 1987-1988 Porsche 944 S 1989-1991 Porsche 944 S2 1986-1989 Porsche 944 Turbo 1988 Porsche 944 Turbo S 2008-2010,2013-2014 Porsche Cayenne GTS 2003-2006,2008-2014 Porsche Cayenne S 2010 Porsche Cayenne S Transsyberia 2003-2006,2008-2018 Porsche Cayenne Turbo 2006,2009-2010,2013-2014,2016-2018 Porsche Cayenne Turbo S 2017-2018 Porsche Macan GTS 2015-2019 Porsche Macan S 2010-2013 Porsche Panamera 4S 2016 Porsche Panamera Exclusive 2013-2016 Porsche Panamera GTS 2010-2013 Porsche Panamera S 2010-2016 Porsche Panamera Turbo 2014-2016 Porsche Panamera Turbo Executive 2012-2016 Porsche Panamera Turbo S 2014-2016 Porsche Panamera Turbo S Executive 1999-2003 Volkswagen Beetle GL 1999-2005 Volkswagen Beetle GLS 1999-2004 Volkswagen Beetle GLX 2001-2002 Volkswagen Beetle Sport 2002-2004 Volkswagen Beetle Turbo S 2000-2001 Volkswagen Golf GLS 2002-2006 Volkswagen Golf GTI 1.8T 2003 Volkswagen Golf GTI 20th Anniversary 2002 Volkswagen Golf GTI 337 2000-2001 Volkswagen Golf GTI GLS 2003-2005 Volkswagen Jetta GL 2004-2005 Volkswagen Jetta GLI 2000-2005 Volkswagen Jetta GLS 2001,2003 Volkswagen Jetta Wolfsburg Edition 2003-2005 Volkswagen Passat GL 1998-2005 Volkswagen Passat GLS 2004-2005 Volkswagen Passat GLS 4 Motion ## Details - **Price:** 434.37 CAD - **Vendor:** APR - **Type:** Blow Off Valves ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 434.37 CAD | In stock | ## Images - Photo - Primary - Photo - out of package - Installation Instructions - Photo - out of package - Photo - out of package --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/apr-audi-porsche-volkswagen-r1-diverter-valve) > Updated: 2026-07-15
