The mountune MRX Turbocharger Upgrade for the 2014-17 Fiesta ST
offers greater power output with minimal increase in turbocharger lag, which
greatly enhances the driving experience.
Tested and validated over thousands of miles for
durability and performance, the mountune MRX Turbocharger Upgrade includes all required
hardware, fittings and hoses along with engine calibration for a range of power
levels and fuel types. This upgrade does not require any fuel system upgrades
and is compatible with both 91, 93, and 94 octane fuel. The Fiesta MRX Turbocharger Upgrade has been developed for those that desire a fully engineered upgrade that provides an optimized power band. Unlike other upgrades that deliver just peak or high RPM power, the mountune MRX Turbocharger offers performance throughout the entire power band ensuring a very responsive and drivable car. The mountune MRX Turbocharger Upgrade is designed for those that are looking for well balanced yet extremely powerful performance derived from years of developing race winning Ford 4 cylinder turbocharged engines.
The Fiesta ST MRX Turbocharger Upgrade is engineered around a genuine Garrett GT2554R core that features a custom engineered 11-blade billet compressor wheel and matching 3" inlet ant-surge compressor housing for incredible response and power. Developed as a complete system with everything
available from one source ensures the performance and quality you’ve come to
