Description: Condition: New Type: Blow Off Valve Fitment Type: Direct Replacement Color: Blue Material: aluminum alloy Function : The so-called pressure relief valve device is a device that prevents the compressed air of the turbine from running back in the opposite direction of the turbine through the suction pipe when the fueling is stopped. If the pressure relief valve device is not installed, the turbine blade will be damaged by impact. Advantage: 1. Enhance the pressure relief valve relief, effective protection 2. Protect turbine life 3. Improve turbine response and enhance power supply response Fits (For the reference): 2008 - 2014 Subaru Impreza WRX (will not fit 2002 - 2007 WRX, please view our other listing for a different BOV) 2005 - 2009 Subaru Legacy GT Package includes: 1x Dual Port Blow Off Valve 1x Gasket 1x Blanking Plug

Quality product with minor tweaking.
2011 Subaru WRX Premium (2.5)Perfect fit for factory tmic and well made. The only issue I had with install; the cone on atmosphere purge side is too broad. It’s very difficult to install without removing right tmic support bracket. Once installed, put rear support tmic bracket bolt in first, then pull front into correct position while turning hybrid bov counter clockwise for clearance. Holding the front of the bracket to install two bolts will keep bov still while you tighten up.The vacuum connection will move when you adjust spring tension, so use 13mm wrench to loosen until you get correct tension, then tighten it, reconnect vacuum and you’re all set.

Maybe not for people running high boost
I have an upgraded intercooler and fitment was ok. I had to remove the trumpet to make it fit, but im not basing my rating due to that. I am running stage 3 on my 08 wrx at about 20psi. I compared the spring tension to the stock and felt that the stock bpv had more spring tension. This is already with the setting set to its tightest on this new one. My car now backfires more even at a slight spirited driving. I opened up the bov and added shims to tighten the spring up some more. Im hoping this does the trick.Edit Update:So the piston seem to be getting stuck. At first i thought maybe its the the weather with the metal slightly expanding/contracting but after about an hr in my commute, i gave it some boost to hear it. It did not go off. I did a few WOT (20psi) pulls and still nothing. Finally when I was close to home it finally got 'unstuck' and I started to hear it as intended. Usually i would hear the 'psshh' sound even at 5psi, but when its stuck you dont hear it at all. I had to open it up and inspected the piston for any debris. It looked properly lubed but I cleaned it up anyway and applied grease. If this doesnt do the trick then I will need to take it off and put the stock bpv on. Im sure its not healthy for the turbo with the pressure not escaping anywhere when it gets stuck.

Not impressed.
1. No gasket included! Not a good start. Had to purchase gasket from Subaru dealer. 2. Unit was clearly used. It is scratched up with bolt marring as though they took a returned item and shipped it directly to me. 3. No instructions. 4. The BOV seems to be working as advertised.

Quality seems good for price
Didn't notice any gains. Quality seems good for price. Ended up returning not wanting to risk boost leaks

Fit it on my 08 wrx
I love how it looks, the harder or softer adjustment is great and is legit you can feel the spring adjust. It looks great from stock an is a huge upgrade in fitmemt. It has no leaks and love it

Worth the buy, would suggest it over ones similar for double the price
Was a little skeptical at first with the price being so low but surprised me on how easy the install was and how well it worked with just minor adjustments to the spring tension

8/10
ordered it for my 2011 WRX (sedan) & it fit perfectly, besides the cone (which I assume only serves to aplify the sound.) Overall, very satisfied. 💯
