Champion Copper Plus Product Line Overview

The Copper Plus line from Champion focuses on spark plugs that combine copper core technology with nickel alloy electrodes to enhance conductivity and wear resistance. This product line is tailored for small engine use, providing a balance of performance and longevity. The Champion Copper Plus 853 spark plug exemplifies these qualities, making it suitable for a range of small engine applications requiring reliable ignition components.

Technical Details and Specifications

The Champion Copper Plus 853 spark plug features a single ground electrode made from a nickel copper alloy, which improves electrode life and consistent spark delivery. The center electrode diameter measures 0.078 inches, contributing to efficient ignition. With an insulator height and projection of 0.06 inches, the plug maintains proper insulation and heat management. The flat seat design ensures a tight seal in compatible engine cylinders, while the 0.375-inch reach fits many small engine combustion chambers. The spark plug’s thread diameter of 14 mm and hex size of 19 mm allow for compatibility with common small engine models and ease of installation using standard tools.

Applications and Problem Solving

  • Restores reliable ignition in small engines experiencing misfires or hard starts
  • Improves combustion efficiency in lawn mowers, generators, and other small engine equipment
  • Addresses fouling issues caused by worn or damaged spark plugs
  • Helps maintain consistent engine performance under varying operating conditions
  • Suitable replacement for spark plugs with similar heat range and thread specifications

Installation Notes and Tips

Before installation, verify the spark plug gap is set to the specified 0.020 inches (0.50 mm) to ensure optimal performance. Use a 19 mm socket wrench to install or remove the spark plug, taking care not to overtighten to avoid thread damage. The flat seat design requires proper seating torque to maintain a secure seal. The removable nut electrical terminal allows for flexible connection options depending on the ignition system setup.
