Make sure you check that it comes with an O-ring for where the flange and bov meets. You wont notice that it leaks until you do a boost leak down test. Mine didnt come with one so i called RSD and they sent me one. Bov is great and RSD is awesome. Will always buy from them. Easy install, fits perfect.

Q: in/Hg at different altitudes. uriahbuffalo09260 2 years agoAnswer
Hello! I noticed different springs correlate to different vacuum readings. I live in Tahoe above 6200 ft, and my vac pressure is around 18.5 in/hg. However when I take a trip down near sea level my vac pressure changes all the way to around 22.5 in/Hg. I am guessing I would want the spring rated for my pressure at sea level? Thanks.
A: Base your spring upon where you do most your driving. Readings will always fluctuate based upon elevation but they shouldn't change enough to drastically change performance. http://www.tialsport.com/documents/w3_tial_qqr_sp.pdf

A: This BOV comes with the 11 PSI spring, and if you are pulling -16in/hg to -19in/hg vacuum at idle, then the plain/unpainted spring is recommended.
