NGK SURFACE GAP SPARK PLUG 6431 BU8H 6431

NGK SURFACE GAP SPARK PLUG 6431 BU8H 6431 {"features":"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;","description":"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 colder applications, but may be necessary in high compression applications.","descSource":"p"}
