NGK SPARK PLUGS Spark Plug - LMAR9AI-10 93188

A spark plug might seem like a simple component, but it's the ignition point for engine performance—literally. The NGK LMAR9AI-10 is engineered with materials and construction methods that resist fouling, corrosion, and premature wear, ensuring consistent combustion cycle after cycle. Whether you're running a street engine or pushing limits on the track, reliable spark delivery is non-negotiable.

NGK's trivalent metal plating and pure alumina silicate ceramic insulator are built to handle thermal stress and prevent the misfires that cost you power and consistency. The copper core and corrugated rib design work together to manage heat efficiently and eliminate flashover—keeping your ignition system stable under demanding conditions.
