HKS Super SSQV4 Blow Off Valve Kit w/ Suction Return

Description:
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 sounds in the industry.  Made from ultra-high quality aluminum, along with the highest quality components on the market, this valve is not only designed 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.
