Frequently Asked Questions

How often should I replace my spark plugs?

The replacement interval depends heavily on the plug material. Standard copper plugs usually last 30,000 miles. Platinum plugs are good for 60,000–80,000 miles, and premium iridium plugs can last 100,000 miles or more. Always check your vehicle’s owner manual for the recommended schedule.

Do I need a special tool for spark plug removal?

Yes, you need a specialized spark plug socket. Unlike standard sockets, these have a rubber grommet or magnetic insert to hold the plug securely during removal and installation, preventing damage to the ceramic insulator.

Are pre-gapped spark plugs reliable?

Most high-quality plugs, like those from NGK and Bosch, come accurately pre-gapped for common applications. However, transport can sometimes shift the gap. It is best practice to verify the gap with a feeler gauge before installing, especially for performance or double iridium plugs which can be damaged if gapped incorrectly.
