Plug & play (Genuine MAC variant) 3 port boost control Solenoid for the 05-11 Ford Focus ST and 08-12 RS 2.5 Turbo models. This extremely compact Solenoid plugs straight into the original Ford wiring harness without any wiring modifications making installation very easy. This unit is supplied brand new and can be easily fitted without the need for further software modification and will instantly provide enhanced & reliable boost control.

The standard Ford boost management system relies upon on a basic and inefficient factory solenoid that repeatedly proves to be unreliable and a well known performance weak point. The R-Spec plug & play (MAC Automotive Grade) 3 port boost solenoid valve is a true performance solenoid that is rated to hold boost pressures above and beyond levels that any petrol turbocharged engine is ever likely to see, so fitting this uprated boost control solenoid will also cater for future power/tuning upgrades without the need for further expenditure on additional boost control.


The R-Spec Plug & Play Solenoid only fits the following vehicles:

Ford Focus ST 2.5 Turbo 2005-2011

Ford Focus RS 2.5 Turbo 2008-2012

Ford Focus RS / ST Plug & Play 3 Port Boost Solenoid
