Aftermarket Blow off vavle

[jessetooslow]

I was just wondering if you put a aftermarket blow off valve on a factory car, does it improve performance at all?

 

[jpeek29208]

nope

Neg....it's purpose is to make a WAY cool sound! Yea!!! :sarcasm:














It simply helps prevent compressor surge in the intake system.

not unless your stock one is boned

its actually likely to decrease performance unless you recirculate it back to the intake (most people dont recirc, so everyone down the block can hear that awesome sound.....)
