Help Support 4GTuner:

I think the flange is the same on the VR4/evo8 BOV, you just need an adapter (I believe it's another flange with a metal pipe attached)
 
yea the plastic one leaks at 10psi, max boost i can get is 11psi (normally 15 with the ARC bov)

mr ones are the go i reckon

proven to hold lots of boost and looks stockish

x2. Unless you want the "ricey" sound, I can't see why you would go past the MR BOV. They are a direct replacement for the pastic BOV and can hold well over 20 PSI with no leaks!
 
Yeah, they do make a nice sound however its not as evident at low RPM like most aftermarket units that are still fairly loud even when chaging at 3500 - 4000. If you are trying to keep a low profile, this is not a good idea! :lol:
I'm currently running 22PSI on my VR4 and using the MR BOV, no probs at all.. I was running the std EVO8 plastic one before and was definately leaking up around 18-19PSI.. Replaced it with the metal one and its all good..
