TIAL Q BOV spring
So I have done my research, and have read the spring pressures, which I am not sure if I understand it correctly, based on vacuum correct?
But what I didn't find out is, what comes standard in a TIAL BOV for the 335i? I am amusing its adequate for COBB S1 and S2?
I have found nothing definitive during my research.
