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 Ruthenium LTR7BHX is premium spark plug that is one step colder than the original spark plug and perfect for those running additional boost pressure and typical bolt-on modifications and E30 tuning

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