2015-2020 Subaru STI Blow Off Valves

A blow off valve (BOV) goes under many different names such as dump, bypass, recirc (short for recirculation), diverter, and pop off valves. The stock blow off valves on the 2015-2020 Subaru STI's are not only quiet, they're prone to failure and leakage when you start stacking on boost pressure with tuning and other modifications. Aftermarket BOVs give your aggressive Subie a true, vent-to-atmosphere sound that is sure to turn some heads and feature a high-quality construction that's more reliable than your stock BOV. We have all types of high performance blow off valves you can add to your fast 2015-2020 Subaru STI race car. Your stock blow off valve can only handle so much pressure, so why not upgrade and unlock more potential for your Subie? Check out what we have below!
