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

Features:
  • Smoother acceleration

Reviewer: Tyler Connelly from SeaTac, WA United States  
Not just on the spark plugs and bushings I also bought a B7 kit and some other goodies but Edward N. helped me and he was fantastic! Took the time to answer my questions, get the product shipped asap, and communicate with me. Couldn't be more satisfied with the service and the product. Thank you guys so much! I look forward to much working with you all again.
