whoosh Blow Off Valve Adapter Fiesta ST 2014-2019 *FREE SHIPPING*

At first, I was sort of skeptical because the price just seemed too good to be true because of the boomba racing price but after having it on for over a week. It is easily the best thing I’ve bought on the car since I bought the car!!! Don’t even hesitate. Neck snapper guaranteed

Install took 15 mins, I love that it take your existing intake sound behaviour/characteristics and simply amplifies the sound.

Does this give you the infamous stustustu sound you hear on every turbo? No it doesn't. Is it a good piece of engineering that'll put a smile on your face? Absolutely! If you're like me and will be on stock turbo for awhile but still want something that's easy to install and will put a smile on your face then this it! Relatively easy install! Ron and the woosh team did a great job with this!

If you want to turn heads and let everyone and there mother kno your little fiesta don't mess around this is the Ultimate mod. This could be whooshes calling card. Install is a lil tricky but, if u have the right tools it takes about 15mins just in a hard to get place

This blow off valve adapter is much better than the Boomba racing product for the price and makes the drive so much more enjoyable! After installing and driving around in my little part of town, I was turning heads within an instant! This paired with Jason at Dizzy Tuning's Stage 2 and a pop map, my car is so much easier to smile in. (like it wasnt easy before!) Great job Ron, and i will be purchasing through here for a LONG time!!!
