CHAMPION C61 CHAMPION RACING SPARK PLUG CCH688

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.

Suppressor - Q

• 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.

Racing Specifications:

• Exceptional combustion and strength
• Withstands extreme operating temperatures and pressures
• Same spark plugs represented by professional race cars and trucks
• Projected surface gap design optimizes spark location and eliminates gap growth
