I just got a 98 S4 recently and am wondering if there is a blowoff valve that won't negativly affect my engine. i've been reading posts and some say that you shouldn't put it on and some say that you should. What should i do?

 

I think this week is national blow off valve week, i've seen this question on here in atleast 3 different posts, audi's can't do the bov thing, unless your running stand alone. That is metered air you'd be losing with a bov, the engine ecm has calculated fuel for that air, and if you expell it...your going to get backfires, C.E.L., i've seen some that say audi/vw safe and vent part of the intake charge. I'm not sure about there, never really seen a post saying they work well, your still losing metered air so I'm sure it's not going to run real well.

NO!

You need to tune for it, to run a BOV.

 

If its sound you want, then keep your current setup or do DV upgrades (Bailey's or Forge) and get these:

j/k, someone told me about these things and I googled it and its true! they make BOV sound generators!!

 

people people people, If searching is too much for you, I understand. If moving your wrist to scroll down to see the 15 blow off valve posts that came before yours is too strenuous of an activity, get a mouse with a scroll ball. But, the sad sad fact is that there is no searching involved, no! Not even scrolling through a page plays a roll in this game, no! All the blow off valve posts are at the top of the forum! That being said, I run 4 blow off valves no problem; go for it!

 

ok look at this guys name...... and 1st post.... its obviously someone being gay... just get us all up in a hissy.... nice try.... CHIEF

 

Buy a ricer if you want a f[sm=smiley35.gif]ing BOV.

BOV and S4 do not belong in a sentence together if 'bad' isnt included with them

 

i just wanted to know if it was going to negativly affect my engine if i installed one and i didn't want any of your smart *** remarks

 

Buy 4 and you will be fine. The extra 2 will make up for the CEL.
