search on here for recirc vs vta, esp with the hks. theres prob a billion threads on why you want to do it vs not. covered hundreds of times. this thread will prob get closed, so in before that.
search bar blows, so go to google and narrow by evom.
unless your running SD, you want to recirc. our cars run like crap vta and is all for sound. dont take my word for me, like i said, search. gl

It blows off the remaining air that would otherwise be recirculated back into the intake track. Our cars have metered air flow so it dumps in that much fuel for how much air is missing. It causes the bad idle, dying when clutch is in right after a blow off, and richness between shifts and any other time the BOV releases. If you vent, it is nothing more than a show off valve and has no performance attire at all.

But as others have stated, recirculating will keep your car from running rich between shifts. Some people notice this more than others.

I have to disagree with this statement. When you recirculate the air it's going to take the path of least resistance. If you push it back into your intake pipe it's going to try and charge the pipe (pressurize it) so the air will rush in and try to enter the turbo but will also flow out the filter where there is almost no resistance. So if the air reaches the turbo and encounters resistance, it will go back the other way and exit out the filter side. This is why you can hear the blow off valve much more with an open filter as opposed to a stock type of filter.

I used a HKS BOV that VTA, The sound is not worth it. Another thread I read awhile ago said that you get a 2% performance increase while recir. but fuel consumption was the most noticable change. MPG was down quite a noticable amount. I.E. I was getting 20-30km less off the tank.
