The NGK DIMR8C10 Iridium spark plug delivers precise ignition, improved throttle response and extended service life thanks to NGK engineering and an ultra fine iridium centre electrode. Designed for demanding engines that require a consistent, high energy spark, this spark plug reduces misfires and improves cold starting while helping to maintain fuel efficiency. Its refined firing end and solid construction resist wear and fouling so you get reliable performance across a wide range of operating conditions.

• Electrode material 0.6 mm iridium fine wire centre electrode for a stable and concentrated spark
• Ground electrode design enhanced for long life and consistent ignition
• Heat range 8 optimized for common small engine and motorcycle applications
• Thread diameter 10 mm and reach 19 mm for compact combustion chambers
• Hex size 12 mm for standard socket fitment and easy installation
• Pre set gap 0.7 mm for out of box readiness and optimal spark formation
• Internal resistor for radio frequency interference suppression
• Durable corrosion resistant plating and strong insulator for reliable sealing

Whether you are replacing worn plugs or upgrading to a longer lasting option, this iridium plug balances performance and longevity. It is suitable for many light duty and motorcycle engines that specify a 10 mm thread and heat range 8 plug. Install following manufacturer torque and gap recommendations for best results and enjoy improved throttle response, smoother idle and reduced plug replacement frequency.
