Product Description

Installation Manual

*For USDM [MAP Tuned] Spec Vehicles*


No aftermarket tuning required. Will work on stock tune or aftermarket tunes.


This high performance VTA (vent to atmosphere) blow-off valve is precision machined out of aircraft grade billet aluminum. It features an internal brass piston design and is pressure tested to withstand up to 70psi, allowing it to compliment even the most aggressive turbo builds. Spring pre-load determines the pressure differential required across the piston before the BOV opens and releases the pressurized intake charge. Designed to be a replacement for the OEM bypass valve and is available in 4 different colors.

Installation is simple and all mounting hardware is included.

Compatible with ONLY the Ford 2.0L EcoBoost OEM Turbo. For aftermarket turbo set-ups, please see our Universal Blow Off Valve

    Title of the review says it all. Perfect addition to my car. Next up will be the Boomba Wing Risers (when my budget allows me).

    Great product, great quality, great service.

  5. a good pick 5 Star Review

    Posted by on 26th Oct 2016

    It works well, very well made, easy install only took me about 20 min
    I will say it does release the air pressure ever time there is any little bit of bold up of pressure.

    The boomba bov to my knowledge has the best quality and sound available. All the reviews and forums I've read tend to have the same opinion. I am very pleased with the purchase.

  9. boomba racing back at it again with the best parts! 5 Star Review

  10. Quality product! 5 Star Review

    Posted by on 22nd Apr 2016

    I'm relatively new to the Focus ST world, but I am glad that I came across Boomba. I installed my 3rd Boomba Racing part on my car last night (a BOV) and I am once again impressed. The part looks nice, but also fit just as I would expect it to.

    One of the aspects of Boomba that I really like is the installation videos. They cover what they need to cover, without being super long. They certainly make the installation process much easier because I know just what to expect.

    Shipping is always quick too! Thanks Boomba!
