Locate the Allen screws inside the lip of the tailpipe on the FMF muffler that secures the FMF Q2 spark arrestor to the muffler.

Unfasten the Allen screws with an Allen wrench and slide the spark arrestor out of the muffler tailpipe.

Remove the FMF Q2 spark arrestor from the muffler and discard the part.

Apply the vehicle parking brake. Pull the hood release to open the hood.

Pull the loose spark plug wire off the spark plug and the distributor cap with your hands.

Push the boot covering the spark plug connector back onto the spark plug wire to expose the connector.

Place a spark plug crimper around the loosened connector with the far end of the crimper sitting even with the end of the connector closest to the spark plug wire. Set the crimper in the jaws of a bench mounted vise.

Turn the handle of the bench mounted vise clockwise to force the jaws of the crimper against the spark plug connector. Turn the handle counterclockwise until the crimper releases from the vise jaws. Remove the crimper from the spark plug wire.

Push the boot back over the tightened connector. Attach the spark plug wire onto the spark plug and the connector located on the distributor cap.

Start with a cooled engine. Pop the hood and find the spark plug wires on either side of the engine.

Pull the wires off and turn one of the spark plug wires by the large piece on the end of it. This is called the boot.

Put a socket into the socket wrench with an extension and put it over the spark plug and turn it counterclockwise until the plug is free. Brush the debris out of the boot and cylinder well with a wire brush. Spray anti-seize compound inside the boot and on the new spark plug thread.

Screw the new plug into the well by hand. Test the spark plug tension with a tension tester tool and make any adjustments necessary with the socket wrench until it meets the requirements delineated in the vehicles owners manual.

Put the wire back in place and turn it a half turn to the left. Next, turn it to the right until the wire locks on the spark plug.

Repeat steps 2 through 5 for the remainder of the spark plugs.

Use your spark plug boot to remove the spark plug from the engine. The spark plug is labeled and located on the side of the engine.

Pull your wire through the looms until you have access to the distributor cap.

Put a mark on the wire about 3 inches from the distributor cap with your permanent marker. Use your wire cutters to cut the wire.

Use the wire cutters to strip the wires about five-eighths of an inch from the spark plug wire and your replacement wire. Use wire nuts to connect the replacement wire with the existing wire.

Crimp the wire nut to make sure the wire nut stays secure. Push the new wire into the distributor cap to complete the installation.

Open the hood of the B2300 and set the hood prop. Remove the negative battery cable from the battery, using a 3/8-inch drive ratchet and socket.

Locate the ignition coil -- the box into which all four spark plug wires are routed from the engine. Follow each plug wire from the coil to the engine by running your hand along each wire; as you do so, remove any wire clips from the wires, using a small flat-head screwdriver. These clips are important for keeping the wires in place, so that they do not short out on anything in the engine compartment.

Twist the rubber boot at the engine end of one of the wires, while pulling it up off the spark plug. Trace the wire with your hand back to the ignition coil, and remove only one wire from the ignition coil. Pay close attention to the direction the wire is routed in the engine compartment, as it will have to go back the exact same way.

Spread the new wires out over the front of the radiator so that you can see the length of each wire. Match the length of the wire you have removed from the B2300 with one of the new wires.

Install the new spark plug wire onto the ignition coil. Route the wire through the engine compartment to the engine. Insert the wire and twist it, while pushing the wire downward onto the engine.

Repeat Steps 2 through 5 to complete the wire replacement on the entire engine. Secure all of the spark plug wires with the clips that were previously removed, snapping the clips closed, by hand. Double-check that each wire is securely pushed onto each spark plug, and onto the ignition coil.

Install the battery cable back onto the battery and tighten the tie-down nut snug with a ratchet and socket.
