This piston operated blow off valve for the Ford Focus RS mk2 is not only the perfect replacement for the OEM valve, which is prone to failure when the engine has been tuned or had an upgrade to the engine management software, but also gives you the incredible sound as you lift off the throttle. The valve is supplied complete with all hoses clamps and tubing to ensure the best possible fit.

The silicone hose used can be supplied in a range of colours selectable in the options above.
