The spark plugs are located at the engine end of these wires, under the plug covers that attach them. On a 4-cylinder engine, spark plugs will be located on the top or side of the engine in a row. On an inline 6-cylinder, they are located on the top or side of the engine head.Similarly, it is asked, how do you put spark plugs in?
Changing spark plugs takes about an hour (for a four-cylinder engine) and will save you at least a hundred bucks in labor. You can use the same old tune-up tools (ratchet, spark plug socket and gap gauge). You should use a torque wrench to tighten the plugs.
