NGK Iridium Spark Plug Set LTR71X-II

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
  • Perfect for high boost street use
  • Pre-gapped by Mountune - Choose your application when ordering!

Great Plugs May 18, 2018
Reviewer: Scott Gagnon from Gilbert, AZ United States  
Came gapped correctly and shipping was quick.  No noticeable difference yet but glad I changed because the factory plugs were all different gaps

Post Head Replacement March 30, 2018
Reviewer: Clinton Coleman from Jacksonville, FL United States  
I recently had the cylinder head replacement done to fix the headgasket problem. The idle was rough prior to this replacement but now it's more smooth and accelerates like when it was new.
