Default blow-off valves...

i am new to the forum and don't currently have an A4 though i hope to in the near future, but i am wondering why nobody says anything about blow-off valves for the turbos in here. my friend has a WRX and thats all he ever talks about it how cool his damn blow-off valve is, do they not make them for the 1.8t and the S4 or are they just too rice to be talked about here?

Default Some ppl run them but it's not good for your car, and if you get an intake you will get the sound

and most BOV's will fit an A4 ppl just don't do it because it uses By pass valves.

No, BOV releases boost into the air, BPV recirculates boost back into the system

Default well, our cars have BPV stock and if you do a search here

you will find that a BOV makes our cars lean, or rich, dont remember which one.

There is a ton of info on BOV's wheather or not it is good or bad for the car. I am not an expert on this sybject. Just got to search the site.<ul><li><a href="https://www.audiworld.com/search/index.html">https://www.audiworld.com/search/index.html</a</li></ul>
