Frequently Asked Questions

Q: Do spark plugs really affect gas mileage on a Honda Accord 4 cylinder?

A: Yes. Worn or improper gaps can cause inefficient combustion, which reduces fuel economy. Fresh, properly gapped plugs help ensure optimal combustion and responsiveness.

Q: How often should I replace spark plugs on a 2006 Honda Accord 4 cylinder?

A: For most stock engines, iridium plugs offer a balance of longevity and reliable performance, though the gains may be modest compared to copper plugs if you don’t push the engine hard.

Q: Should I gap plugs before installation?

A: Yes. Check your vehicle’s service manual for the recommended gap and use a feeler gauge to set it precisely before installation.
