Plug and Wire Change
Tools:
• Floor jack

• 3/8" drive ratchet
• 3/8" extensions of different lengths. Recommended sizes 4",6", 12", and 18"
• "regular" 5/8" plug socket, only necessary if you have headers
• 3/4" open­end wrench (or whatever size appropriate for the above socket)
• "U­joint" 5/8" plug socket, 3/8" drive
• Set of metric 3/8" drive sockets, preferably deep well
• 3/8" U­joint

Materials:
• A good set of spark plugs and plug wires.
• Anti­seize compound
• Dielectric grease
Initial Procedure:
• Remove center caps, loosen front wheel lug nuts
• Set the emergency brake and put chocks under the rear wheels.
• Jack up the front of the car, place on jack stands and remove the wheels.
• Check the gap of the plugs (stock is 0.050"). Also, put a thin layer of anti­seize on the plugs before install.
Doing this will keep the threads from seizing to the head, and make later removal MUCH easier.
• FYI, the plugs are numbered 1,3,5,7 (from front to back) on the driver's side and 2,4,6,8 (from front to
back) on the passenger side.
