  3. 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

  5. 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."

  6. 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!

  7. nice very nice 5 Star Review

    Posted by on 24th Mar 2016

    Sounds loud

  8. love it 5 Star Review

    Posted by on 14th Mar 2016

    Part was easy to install
    Not much of a car guy mechanic wise, but very easy to do
    Has a loud sound and couldn't be any happier

  9. Perfect product for a low price 5 Star Review

    Posted by on 19th Feb 2016

    I purchased this for my 16 Fiesta ST. Pretty easy to install and the only part that was difficult is the tight space. If you have just an allen key it would be very difficult. I have a 1/4" socket set with allens. That made life very easy. product is great and I love it cheaper alternative for the BOV sound

  10. More Smiles, more broken necks 5 Star Review

    Posted by on 12th Feb 2016

    This thing is brilliant, it gave me exactly the aggressive noise i was looking for, to really accentuate and brandish that little turbo. Makes people second take the car every time i fly by, and the finish (red anodize) is impeccable.
