Ngk Spark Plugs

surface gap plugs are nearly immune to pre-ignition, and usually require a special high energy ignition system.They can be susceptible to fouling, especially in bcolder applications, but may be necessary in high compression applications.

trivalent metal plating provides superior anti-corrosion and anti-seizing properties

corrugated ribs prevent flashover

pure alumina silicate ceramic insulator, provides superior strength and better heat transfer

copper core aids in heat removal

triple seals prevent leakage
