Upgrade from the standard plug to NGK’s Iridium series for sharper performance and longer life. The ultra fine iridium centre electrode delivers a stronger, more consistent spark, improving throttle response, fuel efficiency, and cold starting. Iridium’s superior durability means less wear, longer service intervals, and reliable ignition even under extreme conditions. Key benefits over standard plugs:
- Stronger spark for improved combustion and throttle response
- Better fuel efficiency and smoother running
- Easier cold starts
- Longer lifespan thanks to iridium’s high melting point
- Reduced misfires and consistent performance under load
