Forge Motorsport have developed an additional valve for the Ford Fiesta 1.0 Ecoboost. This is a twin piston blow-off valve. Under boost the valve has a clean crisp sound that will definitely get you noticed.
Machined from Billet aluminum the FMDV4 valve is completely tunable and serviceable to keep up with any other modifications as they progress. Installation is simple with full illustrated instructions.
All Forge Motorsport Dual-Piston Atmospheric Valves have been designed and built with the intent of venting 100% of the residual charge air remaining in your forced induction system to the atmosphere at throttle lift.
This valve comes with the Forge Motorsport "No Hassle" warranty.
Please note that due to the position of the air flow sensor on the 1.0 Ecoboost engines this valve may on occasion cause the EML (Engine Management Light) to illuminate. This does not have a detrimental effect on the engine and will disappear when the ignition is switched off and on again.
The valve was tested under a range of conditions in stock and mapped models where EML was only induced under heavy load, extraordinary to normal road driving conditions. Given that hard driving is quite often outside the parameters of legal road usage we of course do not recommend driving in a fashion that might induce EML mode.
