Product Details
Champion Copper Plus is the brand’s copper-core spark plug line, focused on steady spark delivery and controlled operating temperature. This part number 13 spark plug uses a nickel copper alloy ground electrode and a nickel center electrode tip to support reliable ignition performance in everyday driving conditions. It cross-references NGK 4013 and Autolite 605 for the same application.
Compatible With long-tail applications including 1999-2013 Chevrolet Silverado 1500, 2010-2013 GMC Sierra 1500, 2007-2009 Buick LaCrosse, 2005-2009 Chevrolet Equinox, and 1996-2008 Pontiac Grand Prix. It also appears in fitment for Chevrolet Express, GMC Savana, Ford Explorer, and Buick LeSabre applications across the listed model years.
What It Helps Address
- Hard starting caused by worn or fouled spark plugs
- Rough idle from inconsistent spark delivery
- Misfire conditions related to aged secondary ignition components
- Reduced throttle response from degraded plug performance
- Maintenance replacement for confirmed OE-style applications
Installation Notes
Verify the vehicle’s required plug type, seat style, and gap before installation. Confirm the application-specific gap listed in the fitment notes, since some vehicles call for 0.050 in., 0.054 in., 0.056 in., or 0.060 in. This plug uses a non-removable nut terminal and a 14 mm thread diameter with a 0.689 in. reach.
For best results, inspect ignition wires or coil-on-plug components during service and replace any worn secondary ignition parts before installing the new plug.
