Champion 975 Spark Plug

Champion Copper Plus 975 Spark Plug

Champion Copper Plus 975 is a replacement spark plug built for dependable ignition performance in a wide range of vehicles and small-engine applications. It uses a copper core electrode for improved conductivity and heat control, with nickel center and ground electrode tip materials for consistent wear characteristics.

Key Features

• Copper core electrode for strong conductivity and heat management
• Nickel center electrode tip and nickel ground electrode core material
• Resistor design for reduced electrical noise
• Flat seat construction with a 14 mm thread diameter and 0.625 in hex size
• Pre-gapped at 0.042 in for straightforward service replacement
• Champion Copper Plus small engine classification

Product Details

This Champion spark plug, part number 975, is part of the Copper Plus line, which focuses on practical, serviceable ignition performance. The copper core helps transfer heat away from the firing end while supporting stable spark delivery, making it a solid choice for routine maintenance on vehicles such as Toyota Tacoma, Toyota Tundra, Honda Civic, and Lexus GX460 applications listed in the fitment data. It cross-references NGK 3672 for the same application.

Compatible fitment includes many Toyota, Lexus, Subaru, Volvo, BMW, Honda, Kia, Nissan, and Mercedes-Benz applications across the 2000-2022 model years. For example, it fits 2007-2021 Toyota Tundra, N/A; fits 2010-2022 Lexus GX460, N/A; and fits 2006-2015 Honda Civic, N/A where the listed plug type and gap match the vehicle specification.

What It Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent spark delivery
• Misfire concerns related to aged ignition components
• Reduced throttle response from degraded plug performance
• Maintenance intervals requiring a direct spark plug replacement

Installation Notes

Verify the plug type, thread diameter, reach, seat style, and gap before installation. This plug is listed with a 0.042 in pre-gap, while several vehicle applications in the fitment data specify their own gap requirements, including 0.044 in, 0.043 in, 0.032 in, 0.030 in, 0.028 in, and 0.027 in. Always confirm the engine’s service specification before installation. The electrical terminal uses a non-removable nut.

Quality Assurance

Champion Copper Plus plugs are built around a copper-core design for dependable conductivity and heat control, with nickel electrode materials for everyday service durability. Part number 975 is engineered to meet the listed OE-style applications shown in the fitment data.
