Why Choose a Double Iridium Spark Plug?

Double iridium spark plugs use iridium at both the firing pin and electrode pin. The fine electrode design is intended to support reliable ignition and resist electrode wear.

A correctly specified spark plug helps maintain reliable starting, stable idling and normal combustion. Improvements in fuel economy, acceleration, throttle response or horsepower are not guaranteed and depend on the motorcycle’s condition and setup.

Installation & Maintenance
