When it comes to blow off valves in your Subaru, there are many to choose from, but the HKS valve is the most unique and sought after. Utilizing a pull type relief valve design along with the internal design of the valve, the more boost you run, the tighter the valve seals. With a small primary valve that opens first when you let off the gas, followed by a large secondary valve, it gives one of the most unique and copied sound in the industry.

Made from ultra-high quality aluminum, along with the highest quality components on the market, this valve is not only deigned to withstand ultra-high boost, but it is built to last a lifetime. Easy to install and the kit will come with everything you need, HKS wants to make sure your Subaru will be back on the road in no time.

Kit includes the HKS Suction Return Hose Kit to allow installation as a recirclation valve.

  • Q: Fitment  Fern 6 days ago


    Will this fit my 2008 wrx ?

    • A: This will not fit your 08 WRX, you'll want the universal part with this adapter: Custom tuning is also needed to run an atmospheric BOV safely on a WRX.

    Hello, I have a 2013 wrx I plan on getting BOV but reading and watching reviews I see that when installing do you have to ajust the fuel air ratio so you won't get a trouble code. And how would you do that if you have too.

    • A: A blow off valve does not require you to adjust your fuel trims. The only air being released or recycled back into your intake system is pre-combustion air.

    Hi, does this BOV fit a 2014 WRX? I saw that I need Part#: HKS3 71008-AF012, but the site says this will fit my car. If this part does not fit my car, do you guys have the AF012 in stock? Thanks

    • A: This BOV will fit your 2014 wrx.
