Fine-wire centre electrode and V-trimmed ground electrode produces the sharpest spark focus. Long life and performance that far exceeds conventional plugs.

THERMAL CONTOUR FIRING TIP

Projected Core Nose

• Extended nose projection of the plug creates a longer path for heat to travel.
• The plug stays hot during periods of prolonged idling…preventing cold fouling.
• The plug stays cool at High RPM due to the Charge Cooling effect of the incoming Air/Fuel mixture.
• This gives POWERSPORT a much more dynamic heat range over standard plugs.

Power Boost Firing End

Fine-wire projected electrode design delivers more power and maximum fouling protection. V-trimmed ground electrode keeps spark concentrated through all engine demands.

Q – Suppressor

Wire-wound low-ohm resistor enables full ignition energy to reach the cylinder where it is needed most.

Thermal Contour Firing Tip

Modifies electrode heat transfer to prevent deposits while idling and plug overheating during high-speed operation.
