Little caution for these:
If you have an ets intake you'll have revise to fitting them. What I did was a tiny bit sketchy but it's holding on strong. And the sound I got me excited. Definitely worth buying.

Awesome product showed up quick easy install great sound

Better than I thought it would be

The sound from this BOV was exactly what I was looking for. I would highly recommend this for any car needing a BOV.

Comes with everything you need to install.

Apparently if you have diverter valve and then change to a BOV, you need a retune, but I've been running a BOV for the last 10 years so I don't remember.

Nice but with a catch.

So I was looking into HKS blow off valve and its definitely nice, but with a catch. If you're all stock like I am, you would either need to get a recirculating kit for this HKS blow off valve or a tune as you're gonna be running rich because EVO X are made factory with a BPV (bypass valve) and not a BOV (blow off valve). besides that it's a great product just one thing the brand forgets to mention.

Exactly what i was expecting!

It took hard work trying to find the best BOV money can buy. i dont regret one bit and its easy to install. I love the build up of air when accelerating and then the loud flutter sounds that it makes when its released. I recommend highly
