Want the added strength and performance of our Blow Off Valve but not the biggest fan of the added noise?

Introducing the Boomba Racing Bypass Valve.

This piece is very similar to our Blow Off Valve, but rather than venting to atmosphere, this vents back to intake. 

Also, for all you Europe Spec/MAF tuned cars: THIS PIECE IS 100% SAFE TO RUN!


*For USDM [MAP Tuned] Spec Vehicles and EU [MAF Tuned] Spec Vehicles*



Boomba Racing is proud to announce our Boost Operated Bypass Valve for the 2014+ Fiesta ST.


This kit will replace your weak and leaky OEM bypass valve in favor of something much more up to the job. The Boomba Racing Boost Operated Bypass Valve comes with everything you need to install on your vehicle for a true plug and play installation. It features 100% vent to intake operation and billet aluminum construction with a brass piston to ensure leak-free operation for years to come.


The Boomba Bypass Valve uses an ECU controlled solenoid that provides the bypass valve with both vacuum and boost pressure. Using boost to close the valve keeps it sealed no matter what the boost pressure is. The higher the amount of pressure, the stronger force there is keeping the valve closed. Vacuum is used to keep the valve open in this configuration. This with the combination of the ECU controlled solenoid prevents the valve from any fluttering or premature opening. This also works to eliminate any unwanted pressure spikes during venting. The purpose of this bypass valve is to prevent turbo lag and allow the car to hold boost in a steadier manner. When the throttle plate closes, excess boost pressure is vented so that the turbo can continue to spin during higher RPMs rather than surge from backpressure. The bypass valve is tested to over 75 PSI to ensure leak-free operation. The electrical connection on the provided solenoid matches right up with your factory wiring and there is no need to splice or trick your ECU with resistors.


Don’t hesitate; pick up lost power by replacing your leaky factory BPV with a Boomba BPV, today!


As always this product is designed and manufactured 100% in-house in the USA.


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

  1. Great replacement for the stock valve 4 Star Review

    Posted by on 9th Jul 2018

    I installed this on a 2016 1.6L ecoboost in a Transit Connect (same engine as a Fiesta ST). The installation was as easy as the video shows. The only difference in the TC is I used an existing 8mm threaded stud in the firewall to mount the solenoid valve.

    The BRV makes a nice, mild chirping noise when it bleeds pressure back into the intake manifold. This noise is slightly louder in my TC because I installed a Focus RS air box that has a large hole open to the engine compartment. This BRV is exactly what I wanted...a little audible feedback from the turbo with any annoying blow-off noise. It gets 4 stars for perfect execution but does not appear to improve performance so minus 1 star.
