6. Inspect the old spark plugs.
The old spark plugs can tell you a lot about the condition of your engine. If the spark plugs are worn or damaged, it may be time for a tune-up.
7. Apply dielectric grease to the new spark plugs.
This will help to prevent the spark plugs from seizing in the engine.
8. Screw the new spark plugs into place.
Hand-tighten the new spark plugs until they are snug. Then, use the spark plug wrench to tighten the spark plugs until they are snug.
9. Reattach the engine cover.
Reattach the engine cover and reconnect the negative battery terminal.

Start the engine and let it run for a few minutes. Check for any leaks around the spark plugs. If you see any leaks, tighten the spark plugs until the leaks stop.
