Good To Know

Q: How often should spark plugs and wires be replaced? A: Many V8 engines benefit from a wire and plug change around every 60,000 to 100,000 miles depending on driving conditions. Watch for rough idle, misfires, or reduced fuel economy as signs to replace them sooner.

Q: Does this kit fit all Chevrolet Silverado 1500 and GMC Sierra V8 years? A: Fitment depends on the engine code and model year, so verify your truck's V8 configuration against the 41-962 reference. Confirm plug gap and wire routing before installation.
