What do you guys think of the GReddy Type S blow off valve? I was debating which one to get for my 2003 Mitsubishi Lancer EVO 8, and I think the Type S seems like a good one. I know there is an adapter flange that can bolt right to my stock intercooler piping, so it should be an easy install.

However, I keep hearing that the Mitsubishi Lancer EVO MR blow off valve is a good one too, and its cheaper. Anyone use either on their cars?

Is it true the Type S leaks over 20 PSI?

TIA
