Prevent Boost Leaks and Bump up your WRX or Forester XT’s Performance

Like most stock bypass valves (BPVs), the OEM BPV on your WRX or Forester XT is this sad, plastic and rubber device that struggles to fulfill its purpose under even the most normal stock conditions, much less when your WRX or Forester XT build is running extra boost pressure from aftermarket tuning or other upgrades. The Boomba Racing Billet BPV for 2015-2020 Subaru WRXs and 2014-2018 Forester XTs features a far more durable construction than stock, which makes it far more capable of preventing boost leaks and helps your Subie build maintain maximum performance when you stack on the tuning and turbo mods that increase boost pressure and airflow. Boomba’s BPV comes in a selection of anodized finishes and easily installs in place of your factory BPV as a drop-in replacement.

Boomba builds each of their Billet BPVs for 2015-2020 WRXs and Forester XTs out of high-strength materials that make their BPV a leaps and bounds improvement over stock. Each Boomba WRX Billet BPV features a CNC machined billet aluminum body that’s paired up with a brass piston that makes Boomba’s BPV capable of handling up to 75psi of boost pressure. The Boomba BPV is available in several anodized finish options that lets you match your Subie build or get a high-performance look. The BPV features a 100% recirculation design like the OEM BPV, meaning that it does not require specialized tuning. Boomba includes installation hardware and instructions.

  1. Way better thank stock

    By Alex July 25, 2018

    I bought this after seeing plenty of YouTube videos showing. I like th fact that it doesn’t require a tune. I bought my wrx in May so I’m trying to hold off serious power mods until later, but this added a good smooth punch to the acceleration. Installation is pretty straight forward; follow Boomba’s video and you should be done in just under an hour. I gotta one-car garage and did it solo. I can’t say that anything really snagged me during the install. Jacked the front of the car, undid the splash guard and skid plate, then went to work. The car pulls soooo much smoother and boost holds really good. I highly recommend this part if your looking for an easy way to add more throttle response and smoother acceleration. Side note: I don’t really hear the flutter, but I’m still running the stock intake. I’m also kinda hard of hearing (Marine Corps and growing up riding the subway in NY lol).

  2. Perfect

    Operates as advertised. Love it. Cant get enough of it.

  3. Noticable Difference

    By Trevor September 19, 2017

    I can't hear it fluttering, however I am running a stock intake so that is expected. On the other hand I noticed the car maintaining boost better and creating more boost without pushing as hard. I have no doubt that the torque band has improved.
