Top-rated options offer durable construction, consistent ignition, and extended service life that help keep the engine running smoothly for thousands of miles. Several designs also improve combustion efficiency, which supports better performance under load.

Frequently Asked Questions
Q: How often should I change my Chevy truck spark plugs?
A: Most modern iridium plugs can last upwards of 100,000 miles, but for older trucks or those under heavy stress, we recommend checking them every 50,000 to 60,000 miles.
Q: Can I use performance plugs in a stock engine?
A: Yes! Performance plugs like the Iridium IX offer better ignitability, which can help even a stock engine idle smoother and run more cleanly.
Q: Is it necessary to gap my plugs before installation?
A: Most plugs come pre-gapped, but it is always best practice to double-check the gap with a tool against your owner’s manual before you thread them in.
