Uprated Re-Circulating Valve [Mk2 Focus ST/RS | Mk3 Focus ST]

The mountune uprated turbo re-circulating valve is a direct replacement for the OE component.

Machined from solid aluminium with a piston-type design (compared to the OE diaphragm) the more robust design and material are suitable for vehicles in advanced state of tune.

A diaphragm-design recirculation valve could function less effectively when the pressure differential across the turbocharger compressor housing is increased above the original operating conditions. This can cause the valve to open prematurely, leading to possible turbocharger damage due to increased turbo shaft speed.

mountune's engineers have designed an uprated, more robust valve, that features a metal piston and rubber sealing system. This design also features an uprated spring that improves sealing pressure, which allows the valve to remain closed under high pressure conditions.

This product is compatible with mk2 Focus RS, mk2 Focus ST and mk3 Focus ST.


  • Mounts directly on OE turbocharger
  • Easy installation
  • Suitable for vehicles running increased boost pressure
  • Superior piston type design

    Nice item

    Afetr spending weeks deciding on which valve to buy, i settled on the Mountune one. Mainly because of their reputation. I ordered the valve and fitted it as soon as possible. Fitting was straight forward. Car on ramp, offside wheel off, three retaining bolts undone, vacuum line off and the old valve was out. Fitting the Mountune valve was (obviously) the opposite of removal. Wheel back on and engine start a good un - 15 mins max. There were come queries on the orientation on the valve but rest assured, the 'M' logo goes in the 4'o clock position so the ports match up in the valve and the turbo. I will say to anyone ordering this who's after a bit of noise......this is not the valve for you. Its silent. Its quieter than the stock valve. I have an open cone air filter and intake kit and i could hear the old valve venting back. I cant hear this new Mountune valve at all. Its silent. I'm ok with that. I bought this valve to stop the whisting i had from the stock valve on light throttle gear changes. It might be in my head but throttle seems snappier now and it certainly holds boost a bit better. I would recommend this valve as an upgrade to the stock part for anyone who doesnt want silly noises coing from under the bonnet. Build quailty is great, fitting is easy and it just works.

    The item is a massive improvment compared to the original valve.
