Description of NGK 7669 Spark Plug

Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior anti-fouling. The 0. 6 millimeter laser welded fine Iridium tip ensures high durability and a consistently stable spark and the tapered ground electrode minimizes electrical quenching effect. Longer insulator nose prevents fouling, the corrugated ribs on insulator prevents flashover, and a triple gasket seal eliminates combustion gas leakage. Iridium alloy has extremely high melting point, giving it high durability to heat and electrical wear, perfect for today's high performance engines. Trivalent Metal Plating provides superior anti-corrosion and anti-seizing properties.

NGK spark plugs are the best

I have found NGK spark plugs to be the best for motorcycles. Other brands just can't seem to match the durability and performance. The platinum and iridium versions are at the top of the stack. Go cheap or go to NGK.

Pros
  • One year trial
Cons
  • Available in white only
