Do you need an extension for a spark plug?
Because spark plugs can be in awkward positions, you may also need an extension for your spark plug socket. Choosing one that locks in place may help you avoid the sort of aggravation that occasionally accompanies a spark plug replacement.

Why do you need a spark plug to start a car?
The spark plug is responsible for creating the electricity that ignites the air-fuel mixture in the combustion engine, which starts your car. The plugs set the engine’s pistons in motion and continue to provide power to keep your vehicle moving down the road.

How old do spark plugs need to be?
Re-installing a damaged boot or wire will cause a misfire and possible damage to other ignition components. If the spark plug wires are five to seven years old or have 100K+ miles of use, replacement is highly recommended.
What should I put in my spark plug boot?
Apply a thin coating of dielectric grease around the inside of the spark plug boot before reinstalling the coil. The grease prevents misfires and makes it easier to remove the boot in the future. Reinstall the ignition coil, hold-down bolt and coil electrical connector.
How do you check the gap between spark plugs?
Gap all plugs before installation using the manufacturer’s specs. Always check the spark plug gap before installing it. Slide the correct wire gauge (or gap gauge) between the electrodes. The wire should drag slightly between them. If the gap is too small, open it with the gap gauge by prying up.
