Champion 10 Spark Plug

Champion Copper Plus 10 Spark Plug

Champion Copper Plus 10 is a non-resistor spark plug built for dependable ignition performance in classic applications. It uses a copper core electrode for improved conductivity and heat control, with nickel-based electrode materials for steady wear characteristics. This J12YC plug is a direct match for a wide range of vintage Chrysler, Dodge, Jeep, Chevrolet, Pontiac, Buick, Oldsmobile, GMC, and Toyota applications.

Product Details

The Champion Copper Plus line focuses on straightforward ignition service for vehicles that call for a traditional copper-core spark plug. Part number 10 is built around the J12YC plug type and a 0.035-inch gap, with a flat seat and 3/8-inch reach to match the listed OE-style applications. The non-resistor construction is important for older ignition systems that were originally specified without resistor plugs. This part number 10 spark plug is a practical choice for classic Dodge Charger, Chrysler Newport, and Chevrolet Impala service where correct plug type and heat range matter.

This part cross-references Champion Spark Plug 34 for the same application.

What It Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from weak or inconsistent spark delivery
• Misfire complaints tied to incorrect plug type or gap
• Loss of throttle response in older ignition systems
• Heat-related plug wear in engines that need copper-core control

Installation Notes and Tips

Verify the engine calls for a non-resistor J12YC-style plug with a 0.035-inch gap before installation. Check thread diameter, reach, and seat type against the vehicle specification, especially on older Chrysler, Dodge, Jeep, and Chevrolet engines. Confirm the plug gap during service if your application requires a different setting than the pre-gap value. Use the correct torque procedure for the cylinder head material and ignition system.

Quality Assurance

Champion Copper Plus plugs are built for dependable service in OE-style ignition applications. The copper core design supports conductivity and heat control, while the nickel electrode materials are selected for consistent wear in classic engine use.
