For the price I was a little disappointed. My item came missing parts (vacuum fittings/allen keys/bolts/zip ties). I only received the Valve itself and the two hoses. I made it work though, and other than the fact that you have to reuse your OEM trumpet fitting, this is a really nice part. I'd recommend it and hope that the missing pieces were a one-time fluke.
Great product but the noise is not a significant step up from factory BOV in my STI. Also with this product I'm developing turbo flutter at low rpm boost.
At 100% atmosphere this thing makes a ruckus! It's nice that it is adjustable (in case you get sick of the noise). My one complaint is that you have to re-use part of the return for the old BOV. Not sure if this is because it is different on various vehicles, but it was a real pain to get off without damaging it..
Purchased this and attempted to install on my 2009 STI. Had to reinstall my old recirc valve after attempting to remove the 2 SCREWS(yes, Subaru used 2 garbage quality screws to hold the return elbow to the recirc valve) to swap the elbow to the BOV. After using the correct crossed tip screwdriver with minimal effort, the screws stripped not allowing me to swap the elbow over. The quality of the BOV is excellent. A little over priced to be using recycled parts off my old recirc valve though. Recommend to install if your engine compartment is relatively new and clean with easy to remove hardware.
Took about 15 min. to install and another 10 to adjust. One word of advice is to take your time removing stock Philips head screws on elbow they are made of a soft metal and will strip easily.

A: Honestly just leave it alone unless you've done something that is going to affect the vacuum the engine produces. Ie cams, headwork etc.. Thanks

A: It would depend on which flange is on the intercooler. If the flange matches up it would work great.
