  1. Absolutely nasty 5 Star Review

    Posted by on 11th May 2018

    So far I've only done a few small easy bolt ons and this has to be my favorite next to the rear motor mount only because the RMM really improves the shifting. I work in a downtown area so this really turns heads. Super easy installation, found that removing the plastic belt cover makes it alot easier to get to. I plan on sticking with boomba for most of their upgrades. Next is the ultimate shift kit ;)

  2. Great product, well made! 5 Star Review

  3. Good fun 5 Star Review

    The intstall wasn't easy without a trip to homedepot, but overall I love it!

  4. Great buy!!! 5 Star Review

    Bought this as a Christmas gift and his car sounds amazing!!! Not to mention the customer service and response time is exceptional. Definitely recommending this company to our friends.

  5. Amazing First Mod 5 Star Review

    Posted by on 17th Dec 2016

    This BOV adapter will turn heads even if your FiSTa is bone stock, Shipping was nice and quick! Built very good and strong. I don't have small hands so the install is a bit tricky but nothing to get upset about, make sure to use a Ratchet if you don't have small hands with proper extension. The 5mm extension from Lowes was $5.99. Love this little device and since the Fiesta Boosts fast it makes the Pshht sound with little to no beating on the car! PERFECTION

  7. easy install 4 Star Review

    Posted by on 13th Jul 2016

    Hello all
    I order the boomba bov adapter for my 2015 fist. Fast shipping took about 5 days to get to my house. Took all of 15 mins to install as i had the bov alreay off and ready to go. Sound is not overwhelming. Look forward to ordering more parts from this company

  8. Not real hard to install...with the right tools. 5 Star Review

    Posted by on 14th May 2016

    First of all, let me mention I dreaded this install from what little I've worked on the car up to this point. I know space is tight. However, I was able to install quite easily, even with my large hands. I didn't remove the front wheel, and instead drove my car up on ramps, and had an assortment of hex bits and hex bit extensions plus ratcheting hex bit drivers which made the install not intolerable, and probably better than I expected from underneath. I do recommend adding some blue loc-tite to the thread of the cap screws, though, as done from the factory. Sound is not overly obnoxious, unless you want it to be... under normal driving conditions, it has just the right amount of "psshhhhhhhht."

  9. Not too bad install; Nice sound 4 Star Review

    Posted by on 8th May 2016

    It's only a tough install if you don't have the right tools. I had to go out and get a smaller ratchet and a universal joint to get it. It doesn't help that unless you have a lift, you are working only by feel since you can't see anything. Maybe I just have big hands though lol.

  10. great sound, little dough 5 Star Review

    Posted by on 20th Apr 2016

    Longest part of the install was jacking up car and throwing it on stands. Great sound with my mbrp exhaust and injen intake. Adds that iconic sound that we love about boosted cars. Do yourself a favor and get an extended round hex/Allen on a wobble for your ratchet, otherwise good luck if you've got big hands like me!
