Just wondering if the stock BOVs are necessary to still have on if you already have one seperate BOV. I heard you can take off the 1 but not the other.
And if I take off the the factorys will my car run like crap?
I know they serve a purpose, but dont know why.

 

you can take them off but just plug the openings to the airbox, we dont have maf sensors so its ok.

 

Stock cars don' have two BOV. One is a BOV the other is a CRV (charge relief valve). I don't think you can take off the CRV if you are still running a stock setup w/emissions.

 

I have a intake set up from hks. Also a down pipe..And mid pipe(so plug openings to what?)
yea i heard it wont run good without the CRV.
emissions? whats that
