Iridium Spark Plug Set [Mk8 Fiesta ST | Puma ST | Focus 1.5 | Kuga 1.5]

EcoBoost engines running substantially higher boost pressure or increased levels of tuning compared to the OE power output can experience reduced spark plug life resulting in lower engine performance, misfires and rough idle.

Increased wear is typically seen in the form of increased spark plug gap and degradation of the electrode. Using spark plugs that are optimised for increased power ensures maximum performance.

Extensive in-market validation at extreme boost / cylinder pressures was undertaken to ensure optimal performance was achieved, whilst also making sure reliability and drivability wasn't compromised in colder ambients.

Each set is supplied pre-gapped by mountune to optimise the setting and allow for easier end-user installation.

The NGK LTR71X-II is one step colder than the original spark plug.

  • Fiesta ST 2017-current

    A must have

    Always had Iridium spark plugs and never had any issues with them. A struggle to get because they’re out of stock a lot so you got to be quick!

    Great upgrade from standard sparklers!

    After 20,000 kms i swapped the OEM plugs for the MTune ones. Seems to pick up a bit quicker/stronger. very pleased with product and outcome :-)
