In stock: 10+ psc

Universal Blow-Off Valve (BOV) that works by opening of two exhaust ports. Primary (bypass) port blows back into the intake and the secondary port to the atmosphere (due to sound effect).

Ideal for cars that use in a series Divertet Valve from BOSH. The valve operates as a classic valve from BOSH but opens up at higher pressures. Replacing serial BOSH valve you remove usual ECU problems such as twitching of the engine and you get a sound effect at the same time. Simple plug&play installation, in exchange for the original valve. Inlet and outlet diameter of 25mm.

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

BOV is only suitable for turbocharged engines. Reduces the turbo hole, protects the turbo and creates a sound effect.


You can listen to the BOV sound in the video:

При смяна на клапана и пробег от 70-100км. Дава грешка в компютъра на колата P1128.

    Bohužel sklamání

    Samotný race-shop je dle mého bezkonkurenční - rychlost dodání, dobrá informovanost o zásilce a dobře zabalené zboží. Bohužel blow off ventil nezvládá svoji funkci, při montáži sedl opravdu přesně, avšak s moji motorizací 1.2 tce 74kw (renault clio), neudrží ani provozní tlak turba. Ventil podfukuje a auto padá do nouzového režimu :-(


      Bohužel neudrží ani sériový tlak na clio 1.2 tce. Mám 0.8 baru a propouští
