Greddy Blow Off Valve Type S

[G35cTT]

Greddy Blow Off Valve type S, this is what you need if you're running forced induction.

[350GT]

I ran one of those, briefly. It's more of a "noise maker" than a got-to-have-it performance mod. A cheapo Mistubishi 4G63 blowoff valve with a 1/4" crush will serve the same function at much less than 1/2 the price.

I totally agree with 350GT but I prefer the HKS SSQ because I had a Greddy Type S and it sounded too much of a bird chirp and got annoying. Plus the HKS doesn't leak =)
