Whats a good air intake and bov foe my 2002 wrx?

Cobb short ram with intake box and Cobb XLE Bypass Valve

Agreed with matt. The ej turbo engine you have there honestly doesn't react correctly to anything but cobbs intake and bp valve. You run a full on atmospheric bov your cars gonna run like junk shit.

dylan wtf are you talkin about i run a turbo xs rfl bov it is full atmospheric and my car runs like a dream

what dylan is getting at is if the valve dumps to atmosphere then the car will slightly over fuel as its already metred the air thats going to atmosphere (rather than being recirculated) and fuels the engine appropriately, some people have had their car run shit, but it depends what mods have been made to the car

Most simple answer, there isnt one. All either of those things do at near stock power levels is add noise, if thats all youre after, then go ahead and throw pointless money at the car. http://forums.nasioc.com/forums/showthread.php?t=1602235 http://forums.nasioc.com/forums/showthread.php?t=2158633
