Does my BMW X1 23D, 2012 - Have a BOV/ Blow off valve installed as stock?
I've recently installed a Cold Air intake, and not being so clued up mechanically on cars as of yet I didn't know how to tell if the car had a BOV installed as stock since it has twin turbos?
My next question would be is it worth installing a BOV if it doesn't currently have one, to increase turbo noise and to produce the "whoosh" as it releases air pressure?
