      Guide Steps

      Step 1

      First, you must buy spark plugs that correspond to the engine or their equivalent. Consult the owner's manual.

      Step 2

      Next, you must use a spark plug wrench. Apply force while twisting counterclockwise, until you remove the spark plug.

      Step 3

      Insert the new spark plug. Be careful to not let the new spark plug fall because it can alter the opening of the electrode. It is recommended to use a piece of hose or a wrench to insert it carefully, turning it in a clockwise direction BY HAND to avoid damaging the threads if inserted wrong.
