Champion Copper Plus Spark Plug 328
Champion Copper Plus 328 is a spark plug built for dependable ignition performance in small engine and secondary ignition applications. It uses a copper core electrode to improve conductivity and heat control, while nickel materials at the center and ground electrodes support consistent wear characteristics.
Key Features
- Copper core electrode for improved conductivity and heat management
- Nickel center electrode tip and nickel ground electrode core material
- Nickel copper alloy ground electrode material
- Pre-gapped to 0.032 in. / 0.82 mm
- Flat seat design with 0.5 in. reach and 14 mm thread diameter
- Non-resistor design with removable nut terminal
- Champion Copper Plus small engine classification
Product Details
The Champion Copper Plus line focuses on straightforward ignition performance with a copper core that helps transfer heat efficiently and maintain stable firing characteristics. Part number 328 is identified as plug type L82YC and is built with a 0.813 in. hex size, 82 heat range, and nickel-based electrode construction for consistent service in the correct application. This part cross-references Monroe Shocks & Struts (e.g., 271410, 271411) for the same application.
Common Uses
- Restoring weak spark or inconsistent ignition in small engine equipment
- Addressing fouled plug symptoms caused by worn electrodes
- Replacing a plug with incorrect gap or heat range
- Correcting hard-start or rough-running ignition complaints
Installation Notes
Verify the plug type, thread diameter, reach, seat style, and heat range before installation. Check the gap against the engine specification even though the plug is pre-gapped at 0.032 in. Use the removable nut terminal only when the ignition lead requires that terminal style. For vehicle search relevance, this Champion spark plug 328 is commonly researched alongside Honda Civic and Ford F-150 ignition service terms, but final application should always match the engine specification.
Quality Assurance
Champion designs Copper Plus spark plugs around copper-core conductivity and controlled heat transfer for dependable wear in the specified application. Part number 328 is built to the listed Champion specifications for fit and ignition performance.
