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!

Difference noticed September 28, 2017
Reviewer: Alex Melendez from Tallahassee, FL, United States  
I noticed a difference in fuel economy, even though I'm heavy on the throttle. I noticed less idle vibration as well. Throttle response also is better. Would recommend this product.

Big Turbo! August 5, 2017
Reviewer: Trevor Brown from Corona, CA United States  
Going in with my Big Turbo, had on Stock Turbo but went back to factory heat range strictly for availability at the time. Worked great then, expect them to work great now. NGK is the top dog in Spark Plug, ditch the OEM!
