Detailed Product Description

The Champion Copper Plus 328 spark plug features a nickel ground electrode core and a nickel center electrode tip, providing a balance of conductivity and wear resistance. Its single ground electrode is made from a nickel copper alloy, enhancing durability under typical operating conditions. The spark plug has a flat seat design with a 0.5 inch reach and a 14 mm thread diameter, making it compatible with many small engine models. The pre-gap is set at 0.032 inches (0.82 mm), ensuring proper spark gap for efficient ignition. The insulator height and projection are both 0.06 inches, supporting correct installation depth and electrical insulation. This spark plug does not include a resistor, which is common in small engine applications where interference suppression is less critical. The removable nut electrical terminal type allows for easy connection and replacement.
