The VF Engineering Race Bypass Valve is a direct replacement for the Bosch valve as used on most German factory built turbo automobiles eg VW Golf 1.8T / Audi TT / Porsche 911 Twin Turbo. The Bosch valve is made from plastic and contains a rubber diaphram which is actuated by engine vacuum. The valve is used to release pre-throttle body manifold pressure on deceleration.
The VF-Engineering Race Bypass Valve is made from billet aluminum and can withstand higher boost pressures and the higher charge temperatures. The OE Bosch valve is a part that is prone to failure in stock applications and particularly on ‘chipped’ vehicles. Bosch have revised their valve design several times but by using the VF-Engineering valve you will have the assurance that once this valve is fitted, it will not need to be replaced.
The VF Engineering Race Bypass Valve has been bench “flow tested” and results show that it flows just over 10% more capacity. The greater airflow capacity means that on aftermarket and higher boost applications, air turbulence is reduced and the possibility MAF turbulence is minimized.
- Direct replacement part 90 degree vacuum nipple also available
- Very mild whistle sound on actuation
- Constructed from CNC machined 6061 billet aluminum
