Champion Copper Plus 22 Spark Plug

Champion Copper Plus 22 is a tapered-seat spark plug built for dependable ignition performance and steady heat control. Its copper core electrode improves conductivity, while nickel center and ground electrode materials support consistent wear in everyday driving and classic Ford applications.

Key Features

• Copper core electrode for improved conductivity and heat control
• Nickel center electrode tip and nickel copper alloy ground electrode
• Pre-gapped at 0.040 in for straightforward service setup
• Resistor-type design for ignition system compatibility
• Tapered seat with 18 mm thread diameter and 0.429 in reach
• Champion Copper Plus classification for OE-style replacement use

Product Details

This Champion 22 spark plug is part of the Copper Plus line, a product family focused on practical ignition service with durable materials and stable performance characteristics. The copper core helps transfer heat efficiently, while the nickel-based electrode construction supports good overall wear in engines that call for an RF11YC-style plug. It is a direct service choice for a range of Ford and Mercury vehicles, including Ford Mustang, Ford Thunderbird, Ford Bronco, Ford F-150, and Mercury Cougar applications listed in the fitment data.

This part cross-references Autolite 45 and Autolite 46 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 conditions tied to aged secondary ignition components
• Reduced throttle response from degraded plug performance
• Heat-related plug wear in older Ford and Mercury engines

Installation Notes and Tips

Verify the engine calls for an RF11YC-style plug before installation. Confirm the specified gap for your application; this plug is pre-gapped at 0.040 in, while several listed OE-style applications reference 0.035 in. Check thread diameter, reach, and tapered seat design against the cylinder head before service. Use the removable nut terminal only if your ignition lead requires it, and inspect plug wires, caps, and coils at the same time for best results.
