Champion 7020 Spark Plug

Champion Double Platinum Power Spark Plug

Champion Double Platinum Power spark plug 7020 is built for stable ignition performance in a range of late-1980s through 1990s GM and Mercury applications. It uses platinum on both the center and ground electrodes to support sharper spark focus and longer service life.

This plug is a fitment-based replacement for vehicles such as the Chevrolet Cavalier, Chevrolet S10, and Pontiac Sunfire, with application-specific gap requirements listed in the vehicle notes. The Champion Double Platinum line focuses on consistent firing and durable electrode construction for everyday drivability.

Detailed Description

Champion 7020 is a Double Platinum spark plug engineered for vehicles that call for a tapered-seat, resistor-style plug with platinum electrode materials. The platinum center tip and platinum ground electrode help maintain consistent spark characteristics over time, while the Heat-Active alloy supports reliable combustion performance under changing engine temperatures. This part cross-references Bosch 41928 and Walker Exhaust 41908 for the same application.

Use this plug when servicing ignition systems on applications including 1991-1995 Pontiac Grand Prix, 1994-1996 Buick Century, and 1995-1997 Chevrolet Cavalier. It also matches select Chevrolet S10, GMC Sonoma, Isuzu Hombre, and Pontiac Sunfire applications listed in the fitment data. Search terms such as Champion 7020 spark plug for Chevrolet Cavalier, Champion 7020 for Pontiac Sunfire, and Double Platinum Power spark plug for GMC Sonoma align with this application coverage.

Common Issues This Part Helps Address

• Hard starting caused by worn spark plug electrodes
• Rough idle from inconsistent ignition firing
• Misfire conditions related to aged plugs
• Reduced throttle response from weak spark delivery
• Service intervals shortened by standard electrode wear

Installation Notes and Tips

Verify the engine’s required plug type, seat style, and gap before installation. This plug is pre-gapped to 0.060 in / 1.5 mm, but several listed applications call for 0.045 in or 0.054 in, so confirm the vehicle specification before use. The tapered seat and non-removable nut terminal should be matched to the original equipment configuration, and the plug should be installed to the manufacturer’s torque specification.
