Champion 9810 QC8WEPIA Iridium Spark Plug

The Champion 9810 (QC8WEPIA) is a premium iridium spark plug engineered for maximum performance and longevity. This high-performance plug features advanced precious metal construction designed to deliver consistent ignition across a wide range of engine types and operating conditions.

Key Features:

• 0.7mm fine-wire iridium center electrode for superior spark focus and maximum durability
• Platinum V-trimmed ground electrode ensures longest life and erosion resistance
• Heat-Active alloy reaches operating temperature quickly and maintains stable performance under varying engine loads
• 14mm thread diameter with 19mm (3/4") reach and gasket seat design
• Extended projection design promotes efficient combustion and reduced quenching
• Resistor-type construction reduces electromagnetic interference

The combination of iridium and platinum electrodes provides exceptional wear resistance, with service life up to 100,000 miles. The fine-wire center electrode creates a sharply-focused flame kernel for faster combustion, improved throttle response, and minimized misfires. Ideal for automotive, marine, and powersports applications requiring reliable, long-lasting ignition performance.
