Hi there, thanks for writing in.

The quick and easy rundown of replacing your spark plugs is to carefully remove the spark plug wire from each spark plug, being sure to mark each one so you remember where they go upon reassembly. Then using an appropriate spark plug socket and ratchet, remove the spark plugs by turning them counter clockwise until they come out of the cylinder head. When installing new ones, lightly grease the threads, and turn them in by hand, not using the ratchet. This ensures that they don’t damage the threads. Tighten by hand until they are seated, then use a torque wrench to tighten them to 25ft/lbs. Reinstall the spark plug wires and you’re done. This is also a good time to consider if your spark plug wires, distributor cap and rotor or any other ignition parts need to be replaced. If you would prefer to have this done for you, you can contact a professional technician from YourMechanic, who can come to your home or work and replace your spark plugs and check your ignition system for you.
