*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 100psi, 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.
Available in your choice of color: Onyx Black, Royal Blue, Race Red, or Pure Aluminum

This thing is the perfect addition to any RS. The car should sound like this from the factory. You're not gonna believe the tiny piece of plastic junk this product replaces... LOVE IT! The quality of the product is A1
Factory system seems to be pressurized all the time, so the BOV is constantly in use. Even during casual driving BOV is sounding off.
The piece itself is a great piece. More of a note based on the car the BOV is being installed on (17 RS)
If you want a BOV that rises above the rest then this is it. A great noise and an almost necessary replacement to the horrible little plastic shell that passes as a BOV from Ford.
Weight felt good seals where good paint was good but their was like white scratches I couldn't get off othern then that it has awesome sound its loud and easy to install
Easy install, quality build, good anodizing, and as a side benefit makes pets/animals run like a giant hissing anaconda is coming to fucking eat them. I love the sound and so far is seems to perform really well.
had one in my 14 focus st and loved it and now have a 17 focus Rs so without hesitation i got another one for it. installed easy and got the sound i love back. thx boomba for another great product....
If you are looking for 100% VTA and a solid built product that also looks great.
I actually had a Turbosmart Kompact dual Port BOV installed and I just replaced with the Bommba and It's awesome. waaay louder than a dual port and obviously much louder than the stock valve.
takes about 20 minutes to install. Just raise the right front of the vehicle slightly and remove the front passenger wheel, then it's very easy to access the vacuum line and the 3 Torqx-30 screws. takes about 5 minutes at this point to swap it out.
