mTune MR310 Power Upgrade Kit (Post-facelift)

The MR310 upgrade builds upon the previous market-leading mountune Focus ST MP260 and MR290 power upgrades, additionally adding a revised intake setup and supporting calibration.

The intake adds all of the required induction components from the OE Focus RS setup, including the high-flow crossover, and in addition utilises the high-flow mountune dual-entry air filter, RS500 airbox and snorkel.

The upgrade kit is also supplied with silicone induction hoses and custom wiring harnesses allowing for a quicker, easier installation with no cutting required.

Crucially, the induction changes are optimised by our MR310 calibration which is installed via the supplied mTune handset.

Power is increased, as the kit name suggests, to 310PS, whilst torque increases to 470Nm.

In addition to the required hardware used in the MR290, the MR310 upgrade also adds:

• High-flow Focus RS crossover duct
• High-flow mountune Focus RS airbox (includes mountune Performance badge)
• High-flow dual-entry air filter
• High-flow silicone induction hoses (available in four colours)
• Focus RS GOR (slam panel cover), pipework, battery tray and hardware
• MAF sensor and adaptor harnesses
• mTune handset loaded with MR310 calibration.
