Fiesta 1.0 EcoBoost Mountune MR165 Power Upgrade

The mountune MR165 upgrade is for the mk7 Fiesta 1.0 EcoBoost 125PS and Red / Black 140PS models. 

As the name suggests, the MR165 upgrade kit delivers a performance uplift to 165PS at 6000rpm with 245Nm of torque available from just 2500rpm.

The MR165 upgrade consist of:

• High-flow induction kit
• High-flow primary silicone induction hose
• High-flow secondary silicone induction hose
• High-flow charge pipe upgrade kit
• Larger capacity alloy intercooler
• mTune with MR165 calibration

The MR165 calibration is supplied using an mTune handheld device – for customers who are currently running an MP135 upgrade installed with an mTune, an in-field downloadable firmware update is available at a greatly reduced cost.

mountune's engineers spent a great deal of time developing this kit to ensure that it delivers the optimum level of performance with the OE turbocharger, whilst maintaining the maximum possible reliability of the engine.

The whole kit can be installed in just 2 hours and does not require a ramp / jacking, nor does it require the front bumper to be removed.

The end result is a quite remarkable level of performance that delivers much more than should be capable from a 1.0 engine! 

As well as the impressive low-down torque, the calibration also refines the pedal map to give a more connected, instantaneous response to the drivers' commands.

With the kit installed, the 0-60mph time drops to 7.2 seconds, a massive 2.2-second improvement over the standard model, with in-gear and midrange acceleration improved upon even more so thanks to the 245Nm readily on hand.

As an MR upgrade, your warranty may be affected as it does not benefit from the same warranty provision that the MP upgrades provide. All parts are covered by our standard 12-month / 12,000 mile warranty against manufacturing defects and all of the silicone hoses are backed by SamcoSport's lifetime warranty against manufacturing defects.
