Universal forge style Blow-Off close loop Valve (BOV). It works in a closed loop - blows back into the intake.

Ideal for cars that use a serial Valve Divertet from BOSH. The valve operates as a standard valve from BOSH, but opens up at a higher pressure and which can not be detained by a serial valve. By replacing serial BOSH valve you remove often ECU problems such as twitching engine. Easy installation in exchange for the original valve. Input and output diameter of 33mm (select before ordering). The price includes 3 springs with different hardness (various filling pressure).


Particularly suitable for turbocharged engines of Audi, Fiat, Renault, Peugeot, Saab, Seat, Skoda, VW vehicles.


BOV is only suitable for turbocharged engines. Reduces the turbo hole and protects the turbo.
