Motorcraft Spark Plug Set of 4 - SP-532 Fiesta ST 2014-2016



SP-532

The EcoBoost engine operates under extreme conditions including high cylinder pressures. The spark plugs are subject to rapid wear rates, even at standard performance levels. Engines running higher boost points or increased levels of tune 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.

For optimum power and performance we use genuine Ford Iridium spark plugs and replace them every 10,000 – 12,000 miles.

For standard engines and mountune performance upgrades, we recommend and use standard heat range spark plugs.

  • Genuine Ford Motorcraft
  • Iridium
  • Pre-gapped

Fixed tune issue perfectly June 23, 2017
Reviewer: Mitchel Hamilton from CA United States  
Had an issue with negative corrections after over 20k miles with a custom tune, even in slot 4. Turned out to just need some new plugs, works great again. They did come pregapped to .025 or .026, but I double checked with feeler gauges just for peace of mind.

Don't forget about the maintenance! August 8, 2016
Reviewer: Andrew Valdez from West Covina, CA United States  
Its a good idea to keep an extra set of plugs on hand especially with a turbo charged or any vehicle for that matter. I usually change the plugs around 10k to be safe, its always a pleasure to order from Mountune!
