Champion's copper plus spark plugs outlast regular spark plugs and give more consistent ignition. The Champion iridium plug has a unique semiconductor resistor for optimal EMI and RFI suppression. Champion Copper Plus plugs are V-timed, which means the firing end is V-shaped to improve the plug's ignitability. They have a tiny wire center electrode for precise ignition and a V-shaped ground electrode for better spark focus. Their long-lasting, unique SAC-9 semiconductor resistor delivers maximum EMI and RFI suppression, allowing your vehicle to function to its full potential.

WARNING: CA PROPOSITION 65

Key features:

• Improved ignitability uses a fine-wire center electrode that has been V-trimmed.

• Sharper spark focus is promoted by a V-trimmed ground electrode.

• Under all engine loads, it maintains a constant operating temperature.

• Champion copper plus spark plugs are designed to ISO and SAE standards for long-lasting performance, and the innovative SAC-9 semiconductor resistor delivers maximum EMI and RFI suppression.

• Longer life; the copper core center electrode enables precise management of the plug's heat range, enhancing the plug's function and increasing the spark plug's durability.

• Champion copper plus spark plugs are made with TinTac and Ultraseal Shells, which removes the need for an anti-seize compound during installation while delivering the most satisfactory corrosion protection of any spark plug in the industry.

• The Champion copper plus spark plug has a copper core electrode that improves conductivity and heat control while providing superior overall wear characteristics.
