The Champion 1101S Racing Spark Plugs are engineered for high-performance engines that demand reliable ignition under extreme conditions. These plugs feature nickel alloy electrodes and a projected tip design that positions the spark deeper in the combustion chamber for improved ignition of the air-fuel mixture. Their racing configuration uses a colder heat range and durable construction to help prevent pre-ignition and maintain consistent performance during high-load operation.

Champion 1101S Racing Spark Plugs Features:

• Nickel alloy electrode construction for durability and heat resistance
• Projected center electrode design
• Gasket seat style with 13/16 in. wrench size
• Non-resistor racing spark plug design
