Been doing some reading around this forum and online and a lot of evo 9 owners are saying that the factory bov and intake is perfectly fine when running stock turbo setup. Has anyone running a aftermarket bov, intake notice any deal breaker changes as far as how the car runs and performance wise? or is the factory setup good enough if per say i was looking for 350wheel. Thanks

the ix bov is good to 25 psi and unless you are going for 400 whp on stock turbo there is no need to port the intake manifold. 350 is achievable with bold on's
