hey..
i am looking for blow off for the 2000 s4. i am very new with turbo cars. just wondering if there is any good and reasonalbe price blow off for the 2000 s4. and it is twin turbo so do i have to buy two of them?

 

doesnt use blow off valves...uses diverter valves.. where it expells the gas into the exhaust instead of the atmosphere. The blow off valve isnt thought highly of in the Audi or euro community.. sounds too cheap.

 

not only is it cheap it will scre up youair fueal sensors and everything else. buy upgraded divertor valves and leave it alone.

 

Even though the DV's are more effective, I do LOVE the sound of a nice BOV. But yeah, most aftermarket dealers (Autospeed, AWE, etc.) sell diverter valves that are stronger (the OEM ones are rubber).
