Approximate time: 20 minutes

I recommend replacing these one by one so you do not confuse the four.

1. Locate the plastic wire connectors and remove them. (It's a plastic piece that prevents the wires from moving around, they all fit in it like sardines.)

2. Start on the left. Twist to loosen the handle-like end of the spark plug wire that goes into your engine cover. Pull it out.

3. Trace it to the other end and pull that side out.

4. Take new wire and put handle-like end into the engine cover and lead other end into the side of the engine. Make sure they are in securely.

Continue across until all four are done.

Good luck!
