  Q: How to replace spark plug on Toyota T100,1995 through 2004 Toyota Tacoma and 1996 through 2002 Toyota 4Runner?

  A: To replace spark plugs, the socket protects the plug's insulator during installation. The wrench tightens the new plugs to the correct torque. Also, remove one plug at a time, cleaning the area with compressed air. Unscrew the plug with a socket wrench and extension. Apply anti-seize compound to the threads, align it with a rubber hose, and tighten it to the proper torque.
