TURBO BYPASS / BLOW-OFF VALVE, SWIVEL HEAD, VW/AUDI/PORSCHE WITH TURBOCHARGED ENGINES 

Turbo bypass / blow-off valve, swivel head, VW/Audi/Porsche with turbocharged engines

Product Code: 93505 Price: Check Latest Turbo bypass / blow-off valve, non adjustable with swivel head for tight places, VW/Audi/Porsche with turbocharged \n engines. \n This non-adjustable plumb back model (also referred to as a diverter valve) \n is designed to be a direct OEM replacement, and includes vacuum hose extension, \n vacuum hose adapters, and hose clamps. Constructed of a solid aluminum body \n and brass piston, this valve elimates common failures with the OEM valves and \n has large ports for quick response in high boost applications. Boost will come \n on earlier giving an increase in torque at lower RPM. Also included are two extra springs and two shims for cars using high boost levels. The silver spring is pre-installed and should be applicable for most drivers; it has a spring rate slightly higher than the OE valve and can handle boost levels up to 18psi. The yellow spring is suitable for higher boost chipped applications, 18-22psi. The blue spring is a "race" spring and should only be used in very high boost applications not driven on the street - the high spring tension means the valve only opens for short periods. Available in black anodized or polished finishes. Compact design does not interfere with engine covers like \n other valves being sold. Swivel top allows rotation to adjust the hose alignment. Perfect for tight locations as in 2.7T and Porsche Turbo.
