I read the post for the other guy and I would like to say sorry for posting this but I am new to this BOV stuff so I'm going to try and make this quick and to the point. The BOV from the company ttek i think, if i put that in my S4 is that bad like someone said that the car will be pig rich I dont understand like is it going to mess up my car faster or if I drive around with the BOVs making the noise all the time is that bad what happens if I stop at a light the other post someone said the car will die? i just want to be clear on this topic bc I do want to get them I just want to know if its good for my car in a sense that it wont ruin it really fast. (dont get me wrong I love my car and I dont want it to be ruined)
Again I'm sorry to all
thanks

its gona ruin the turbos faster try doing a search in the forums people talk about this stuff all the time everybodys got there own opinion about em.

 

Don't put a bov on your audi. End of.

type bov into the search window and find out why.

 

Agreed. I don't know why this is played out so much, this was just discussed a couple days ago. The consensus is no BOV's. Period.

 

I think you actually can run a BOV if you use a standalone system / BT etc...

but for the standard applications -we use a closed loop system,
so venting into the atmosphere (BOV) is a no no.

youll run rich - (too much fuel to the engine...) which can cause variety of problems..

 

The LLtek one is a hybrid valve.

It is both a DV & BOV. You dial it to give you enough sound & enough back in the intake.

You need 2 so there like $800, that's a lot of $$ for some noise.
