After watching a youtube video it was very easy to install(im new to this). the first time i heard the bypass i was very excited. it sounds so good. im able to hear it with the windows down as well inside.

No flutter

Just Installed the Boomba bpv on my 2018 wrx and there's no flutter??


Thank you for your 5 Star Review of the Boomba BPV for your WRX. The Boomba BPV is a fully recirculating BPV that is a direct replacement for OEM. Installing just the valve does not ensure additional noises. It does however produce better performance and reliability. Enjoy your upgrade!
