NGK Iridium Spark Plug Set LTR71X-I

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.

Application:
Focus ST 2013-2017
Focus RS 2016-2017

Features:
  • Smoother acceleration

Smoother Idle July 26, 2018
Reviewer: Robert R from Woodridge, IL United States  
I installed these plugs with the M380 pack.  I noticed a much smoother idle.  Compared to stock, these plugs are gapped much more accurately.

One of the plugs was gapped incorrectly and had to be adjusted before installation.
