  • All the performance with or without the noise! If cars like yours typically suffer issues such as backfiring and stalling when using a fixed-ratio atmosphere-venting BOV, the Respons can help. By adjusting the venting bias to suit the car you can achieve a blow-off sound without having to put up with the issues. Like all GFB valves, the Respons utilises GFB’s proven TMS Technology to ensure rapid boost recovery on gearshift and optimum throttle response, as well as the ability to withstand boost pressures of 100psi+. Put simply, it can hold more boost than any turbo could produce. How GFB’s patented venting bias adjustment works Twisting the adjusting ring opens up the atmo port, whilst the recirc port is simultaneously closed.This results in possible venting ratios ranging from 100% recirc, right through to 100% atmosphere and anywhere in between. Complete Range of Fitment Options The Respons direct fit bolt-on range covers a huge list of popular vehicles. You can also purchase a variety of hose and flange adaptors for custom fitments. Performance AND sound without compromise! Patented Venting Bias Adjustment system - can be infinitely adjusted between full recirc (silent) and full atmosphere (loud) Change the venting bias simply by twisting the adjustment ring TMS Technology for up to 30% faster boost recovery on gearshift Huge range of direct bolt-on kits 100psi+ boost holding ability Manufactured in Australia in accordance with ISO 9001 Related Videos: ONLY COMPATIBLE WITH: Make Model Mark Variant EngineCodes BodyStyle DriveType FuelType YearFrom YearTo Audi A3 MK1 8L 1.8 T ARZ,AQA,AUM,AGU Hatchback Front Wheel Drive Petrol 1996 2003 Audi A3 MK1 8L 1.8 T quattro AGU,AWD,AQA,ARZ,AUM Hatchback quattro Petrol 1996 2003 Audi A3 MK1 8L 1.8 T quattro AGU,AWD,AQA,ARZ,AUM Hatchback quattro Petrol 1998 2003 Audi A3 MK1 8L S3 quattro APY,AMK Hatchback quattro Petrol 1999 2002 Audi A3 MK1 8L S3 quattro BAM Hatchback quattro Petrol 2001 2003 Audi A4 B5 1.8 T AEB,AWT,ARK,ANB,APU Avant Front Wheel Drive Petrol 1996 2001 Audi A4 B5 1.8 T ANB,AWT,AEB,ARK,APU Saloon Front Wheel Drive Petrol 1995 2000 Audi A4 B5 1.8 T AJL Avant Front Wheel Drive Petrol 1997 2001 Audi A4 B5 1.8 T AJL Saloon Front Wheel Drive Petrol 1997 2000 Audi A4 B6 & B7 Cabriolet 1.8 T BFB Cabriolet Front Wheel Drive Petrol 2002 2005 Audi A4 B6 Avant 1.8 T AVJ Avant Front Wheel Drive Petrol 2001 2002 Audi A4 B6 Avant 1.8 T BFB Avant Front Wheel Drive Petrol 2002 2004 Audi A4 B6 Saloon / Limousine 1.8 T AVJ Saloon Front Wheel Drive Petrol 2000 2002 Audi A4 B6 Saloon / Limousine 1.8 T BFB Saloon Front Wheel Drive Petrol 2002 2004 Audi TT MK1 Coupé 8N 1.8 T AUM Coupé Front Wheel Drive Petrol 2002 2006 Audi TT MK1 Coupé 8N 1.8 T BVP Coupé Front Wheel Drive Petrol 2005 2006 Audi TT MK1 Coupé 8N 1.8 T APP,AUQ,AJQ,ATC Coupé Front Wheel Drive Petrol 1998 2006 Audi TT MK1 Coupé 8N 1.8 T BVR Coupé Front Wheel Drive Petrol 2005 2006 Audi TT MK1 Roadster 8N 1.8 T BVR Convertible Front Wheel Drive Petrol 2001 2006 Audi TT MK1 Roadster 8N 1.8 T BVR Convertible Front Wheel Drive Petrol 2005 2006 Audi TT MK1 Roadster 8N 1.8 T AJQ,ATC,APP,AUQ Roadster Front Wheel Drive Petrol 1999 2006 Audi TT MK1 Roadster 8N 1.8 T quattro BVR Convertible quattro Petrol 2000 2006 Audi TT MK1 Roadster 8N 1.8 T quattro BVR Convertible quattro Petrol 2005 2006 Audi TT MK1 Roadster 8N 1.8 T quattro APX,BAM Roadster quattro Petrol 1999 2006 Ford Focus MK1 RS Hatchback Front Wheel Drive Petrol 2002 2004 Seat Ibiza MK3 1.8 T 20V Cupra AGU,AWD,AQA,ARZ,AUM Hatchback Front Wheel Drive Petrol 2000 2002 Seat Ibiza MK4 1.8 T Cupra AGU,AWD,AQA,ARZ,AUM Hatchback Front Wheel Drive Petrol 2004 2008 Seat Ibiza MK4 1.8 T FR AGU,AWD,AQA,ARZ,AUM Hatchback Front Wheel Drive Petrol 2003 2008 Seat Leon MK1 1.8 20VT Cupra AGU,AWD,AQA,ARZ,AUM Hatchback Front Wheel Drive Petrol 1999 2005 Seat Leon MK1 1.8 T Cupra R AGU,AWD,AQA,ARZ,AUM Hatchback Front Wheel Drive Petrol 2002 2005 Seat Leon MK1 1.8 T Cupra R AGU,AWD,AQA,ARZ,AUM Hatchback Front Wheel Drive Petrol 2003 2005 Volkswagen Bora 1J6 1.8 T ARX,AGU,AUM Saloon Front Wheel Drive Petrol 2000 2005 Volkswagen Bora 1J6 1.8 T AUQ Saloon Front Wheel Drive Petrol 2002 2005 Volkswagen Golf MK4 1.8 T AGU,AWD,AQA,ARZ,AUM Estate Front Wheel Drive Petrol 2000 2004 Volkswagen Golf MK4 1.8 T GTi AGU,AWD,AQA,ARZ,AUM Hatchback Front Wheel Drive Petrol 1997 2005 Volkswagen Golf MK4 1.8 T GTI 337 Anniversary AGU,AWD,AQA,ARZ,AUM Hatchback Front Wheel Drive Petrol 2001 2005 Volkswagen New Beetle 9C, 1C 1.8 T AGU,AVC,AWV,APH,AWU,BKF Hatchback Front Wheel Drive Petrol 1999 2011 Volkswagen Passat B5 1.8 T ANB,APU,AEB Estate Front Wheel Drive Petrol 1997 2000 Volkswagen Passat B5 1.8 T ANB,AEB,APU Saloon Front Wheel Drive Petrol 1996 2000 Volkswagen Passat B5.5 1.8 T 20V AWT Estate Front Wheel Drive Petrol 2000 2005 Volkswagen Passat B5.5 1.8 T 20V AWL,AWT Saloon Front Wheel Drive Petrol 2000 2005 Volkswagen Polo MK4 (9N) 1.8 GTI BJX Hatchback Front Wheel Drive Petrol
