Increased performance with World's smallest Iridium Center Electrode (0.4mm). To increase ignitability, the important point is to let the flame kernel produced by the spark to grow unobstructed. Normally, this can be accomplished by widening the spark gap. However, this causes spark voltage to incre...

Economical performance and improved ignitability over standard NGK Spark Plugs original equipment manufacturer and racer approved. Lowers ignition system voltage requirements. Greater ignitability and performance over conventional spark plugs. Increased fuel economy and lower emissions. Highly durab...

Dependable performance. This Champion spark plug features a copper core electrode that provides increased conductivity and heat control for good overall wear.

Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior anti-fouling. The 0.6mm laser welded fine iridium tip ensures high durability and a consistently stable spark and the tapered ground electrode minimizes electrical qu...
