My new Evo IX, aftermarker BOV?
Evo jason,
I own a IX MR 06 and it came with a metal BOV. Take your drop in filter (testing only) accelerate the car pass 3500 RPMs and let it go. It will Phhhsssshh very nicely!
The drawback is that you will have to flash your ECU for that simple mod or u can damage your engine. Good luck!

I like the sound but don't want to risk the same problems with my new Evo. I've heard good things about other BOVs like Greddy but I've also read that this is a common problem with the MAF setup. Without modifying the intake, what are my options?
Thanks

And no, turbo cars can make the pshh sound, but not stock evo's. They're not meant to. For example, people can eat their own sh*t but they dont, they're not supposed to.
If I change the intake or BOV then it wouldn't be stock

Try out stage 1 first, I think you might stop there. With a IX, you should be pretty close to 350awhp/tq (catless) on a dynojet. If you want faster spool, get buschurs/AMS lower intercooler pipe. The less mod you have the better chance you'll pass emissions when emission time comes. Good luck!

your on the right track Jason, the IX bov is a great product, but you paid for your evo so what you want with it, add neon ground effects too if you want. Going with the staged package is a great idea too. goodluck and enjoy.
evojason- Do not listen to Silk. He is driving an 05 evo. You will see huge gains on the IX with the stage 2. Look at my sig and everyone else's who has a IX with the same mods. Guys, you really should be more supportive. Some people like different things.
