Changing the Spark plugs on this car was the easiest I have ever done!
4 Spark Plugs (NGK (7418) IFR5J11 Laser Iridium Spark Plug) about $10 a piece
Socket set with Spark Plug Socket and extension (a deep well socket may be needed)
Unclip the air filter canister. Remove the front two screws holding the air cover that sits on top of the engine. The back simply pulls out of a slot, but it does take some force. Remove the air hoses as needed. I was able to simply remove the front one that just slides on without a hose clamp.
Remove the Spark plug ignition coil with the socket set. You don't need to disconnect the wiring, just remove it from the spark plug. Remove the spark plug with a spark plug socket. Carefully, insert the new spark plug. You made need to tighten the spark plug a few turns with the spark plug socket, then switch to a deep well socket.
Reinstall the spark plug ignition coil. Reinstall the air cover and air filter canister.
Start up the car and if no problems, then you are good for another 60,000 miles!
