if ya need to ask...follow the black or gray wires that come off the coil packs on either side of the front of the motor, they go to the plugs, pull them off...in your case 1 by 1 and change the plugs.

Trace the black or gray wires from the coil packs on either side of the front of the engine to the spark plugs. Remove the wires one at a time and replace the plugs.
