Detailed Product Description

The NGK Ruthenium HX High Ignitability Spark Plug (90220) features a dual fine electrode ground tip design that improves ignitability by providing a more focused spark. The center electrode tip is made from ruthenium, a material known for its high melting point and resistance to wear, which contributes to longer service life and consistent ignition performance. The copper core center electrode enhances heat conductivity, helping to maintain optimal operating temperatures and reduce fouling. The spark plug’s nickel ground electrode core and standard ground configuration ensure reliable grounding and spark delivery. With a pre-gap size of 0.044 inches and a tapered seat, this spark plug is designed for precise fitment and efficient combustion in compatible vehicles.
