GFB HYBRID TMS Dual Port 20mm Inlet/20mm Outlet 97-05 VW Golf GTI 1.8T

ALL THE PERFORMANCE WITH THE NOISE! The Hybrid valve is back! In 1999, GFB's first Hybrid valve pioneered the dual port design, which was so successful the technology has since been adopted by most other brands. By "staging" the two venting outlets, at low valve lifts most of the air is recirculated. As the car is driven harder, the valve opens further and more of the atmosphere venting port is exposed for a louder sound. As a benefit, this system makes it possible to use these valves on cars with sensitive airflow meters that often suffer issues such as backfiring and/or stalling, whilst still achieving the signature blow-off sound.This Part Fits: Year Make Model Submodel 1997-2005 Audi A4 Base 2003-2006 Audi A4 Cabriolet 2000-2006 Audi TT Base 2003 Saab 9-3 Arc 1999-2001 Saab 9-3 Base 2003 Saab 9-3 Linear 1999-2003 Saab 9-3 SE 2003 Saab 9-3 Vector 2000-2001,2006-2009 Saab 9-5 2.3t 2000-2005,2008-2009 Saab 9-5 Aero 2004-2005 Saab 9-5 Arc 1999 Saab 9-5 Base 2
