Frequently Asked Questions
Q: How often should I replace spark plugs on a Chevy Equinox?
A: Typical replacement intervals range from 30,000 to 100,000 miles depending on the plug type and driving conditions. Check your owner’s manual and consider premium iridium plugs if you see misfires, rough idle, or reduced fuel economy.

A: Yes, iridium plugs have a tougher center electrode, which typically yields longer life and more consistent ignition, especially in modern engines with tighter tolerances.
Q: Can I mix brands of spark plugs?
A: It’s best to use the same brand and type across all cylinders for balanced ignition. If you mix, ensure the heat range and reach are compatible with your engine’s specifications.
