Frequently Asked Questions

Got a question about our automotive spark plugs? Here are a few things people often ask. For anything else, our main FAQ page has you covered.

How do I find the right spark plugs for my car?

Your best bet is our vehicle selector tool. Just plug in your car’s info, and we’ll show you exactly which plugs are guaranteed to work.

Are your aftermarket spark plugs as good as the originals?

Definitely. We only carry parts that are as good or better than the ones that came in your car, but without those dealership prices.

How often should I replace car spark plugs?

That really depends on the type. A standard copper plug is usually good for about 20,000 miles, while a high-end iridium one can last 100,000. Your owner’s manual will have the exact schedule for your engine.
