What is the purpose of anti-seize on spark plugs?

The purpose of anti-seize on spark plugs is to prevent the spark plugs from seizing or getting stuck in the cylinder head. This can be particularly useful in engines made of aluminum, where the difference in hardness between the spark plug and the engine can lead to the plugs becoming hard to remove over time.

Can you damage spark plugs by over-tightening?

Yes, over-tightening spark plugs can cause damage. It can result in the spark plug's threads being stripped or the plug's ceramic insulator being cracked. Both scenarios can lead to poor engine performance or even engine damage. Therefore, it's crucial to follow the specified torque setting provided by the spark plug manufacturer.

What happens if spark plugs are not installed properly?

If spark plugs are not installed properly, several issues can arise. These can include poor engine performance, increased fuel consumption, misfires, engine hesitation, and potentially serious engine damage. It's crucial to install spark plugs correctly to ensure optimal engine function.

How often should spark plugs be replaced?

The frequency of spark plug replacement can depend on the type of spark plug and the vehicle's manufacturer's recommendations. However, a common guideline is to replace spark plugs every 30,000 to 90,000 miles. Always refer to your vehicle owner's manual for specific recommendations.
