Product Details

The Autolite Copper Resistor Spark Plug line is built around OE form, fit, and function for domestic and foreign vehicles where a standard copper plug is specified. Part number 606 uses a standard/regular center electrode design, a single ground electrode, and a tapered ground electrode tip to support consistent ignition performance under everyday driving conditions. For drivers servicing Chevrolet Silverado 1500, GMC Sierra 1500, or Chevrolet Impala applications, Autolite 606 provides a direct-match spark plug option when the vehicle calls for this gap and seat style.

This part cross-references NGK 4013 for the same application.

Common Problems This Plug Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent spark delivery
• Slow throttle response during acceleration
• Reduced fuel economy from degraded ignition performance
• Misfire concerns tied to incorrect plug gap or worn electrodes

Installation Notes and Tips

Verify the vehicle’s required spark plug gap, seat type, thread diameter, and reach before installation. Autolite 606 is pre-gapped at 0.060 in. / 1.50 mm, but final confirmation against the service specification is recommended. Use the correct torque procedure for the tapered seat design and inspect ignition wires or coil boots during service to avoid repeat misfire issues.
