forge diverter valve spacers
First off, if you run a BOV on your S4... Don't post here.
2nd, check out DV's.
Forge makes DV's but I didn't know there was ever a thing called a DV Spacer.
I think your friend is messin with you.
Tell him you need to repair your flux capacitor before you do anything.
Also, if you have Forge DV's in your signature, why are you asking? I'm confused...
