NGK Iridium Spark Plug Set LTR71X-II

Pre-gapped by Mountune.

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 tuning 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 optimized for increased power insures maximum performance. Includes pre-gapping by Mountune to optimized setting.

The NGK LTR71X-II is one step colder than the original spark plug and perfect for those running additional boost pressure and typical bolt on modifications.

Price is for a set of 4 and includes gap setting !

Application:
  • Focus ST 2013-2018
  • Focus RS 2016-2018
  • Ford Ranger 2019+
Features:
  • Smoother acceleration
  • Perfect for high boost street use

I've had these installed on my motor since I began modding my ST 7yrs ago. Never any issues. Perfectly pre-gapped. Does the job they're intended to do.
