NGK LKAR8BHX (91784) Ruthenium HX Spark Plugs are engineered for modern engines that demand high ignitability, durability, and efficient combustion. Built with NGK's advanced Ruthenium HX technology, they deliver consistent performance, quicker starts, and smoother operation across a wide range of driving conditions — whether you daily drive, track, or mod your ride.

Patented ruthenium alloy center electrodes and advanced tip geometry produce a more complete fuel burn, translating to quicker throttle response, a smoother idle, and improved cold starts. Ruthenium also resists wear and corrosion better than conventional precious metals, so performance stays stable over a long service life — all while matching or exceeding OEM specifications for a true direct-fit replacement.
