If you want to hear the sound then get a BOV. 90% of the people on the forums will scream 'dont get a bov if you want your engine to last'. But they're just reciting info like parrots. I'd suggest researching it and making a decision for yourself. Tons of people run BOVs without any problems. A 100% recirc BOV will give you best of both worlds I suppose. Anyway, good luck and welcome.

A 100% recirc is going to do the same thing the stocker does. If you want the noise - get a decent intake that isn't known to mess with MAF readings. SPT, Cobb, and K&N are known to work fine. I have the K&N. The larger filter/piping combined with the lack of the snorkus/silencer will result in a more discernable noise.

Also, not all of us are 'reciting info like parrots'. Do the research, it's a well known thing that MAF systems do not like BOV's and that they generally react poorly. Stalling, rough idle, and increased afterfire are some of the easily detectable problems that installing a BOV on a MAF equipped car will bring. Cylinder wash and increased oil consumption are results that you won't be able to detect but are still very real issues which should be avoided.

This is not saying that you can't put a BOV on your WRX. However, all it will do is create a noise and the unfortunate conditions I've mentioned above. Air which should be going to the Engine gets diverted to atmosphere after it has been measured and accounted for with fuel. Air goes out, fuel goes in - not good. If you really want to run a BOV, either keep an eye on the cars oil, and use a hybrid type BOV which allows diverting some of the air back into the intake to help lessen the issue; or use an aftermarket tuning solution such as UTEC or OpenECU to convert the car from MAF to MAP. Manifold Absolute Pressure type systems are better able to deal with BOV's however, MAP is older technology and MAF is considered the better way to go.

Either way, it's your car - have fun.

You're in that other 10% . I'm just suggesting he does his own research and comes to his own conclusions, that's all.

Alright, I'd much rather go the safer way.. I'll just go get an intake. haha

i have a ?? for you. i know that venting 100% to atmosphere is bad (experience with RFL bov) but do you know if running a recirc bov will make the car run the same as stock??
