Hello,

You will have to remove the intake assembly to be able to remove the spark plug. You can also go about it from the ignition coil. To replace the spark plug, please follow the steps below to do so. You will be needing these instruments: Phillips screwdriver, Socket wrench, Spark plug socket, Anti-seize compound, Dielectric compound, Small screwdriver, then follow the steps:

1. Disconnect the car's negative battery cable at a time when the engine is cool.
2. Unscrew the individual ignition coil using a screwdriver and then remove the coil and set it aside.
3. Pull out the spark plug wire at the plug end, grasping it by the boot and twisting it out; a special tool for this is available. Disconnect the same wire at the ignition coil.
4. Clean out the spark plug's hole, using compressed air to blow out all dust, dirt and debris from inside.
5. Remove the spark plug from the engine using a socket wrench with a spark plug socket; turn the plug counterclockwise to remove it.
6. Apply a thin coat of anti-seize compound to the threads of the replacement spark plug. Make sure you get no compound on the plug's electrodes.
7. Thread the spark plug into its hole, making sure you don't cross-thread it, and then tighten it with the wrench and spark plug socket.
8. Coat the insides of the spark plug boots with dielectric compound; use a small screwdriver to apply the compound.
9. Install the ignition coil and screw it into place.
10. Repeat the above steps for each spark plug/wire that needs changing and installation.
11. Reconnect the negative battery cable once you've installed all necessary plus and wires
