gently remove the spark plug wire/boot off the plug (they require a good tug to "pop" off) remember which one goes where, OR, change one plug at a time leaving the boots on the other 3 plugs
using a proper sized spark plug socket and ratchet (it has rubber inside to protect the porcelain on the spark plug) remove the old plugs
make sure the new plugs are the correct ones and have the proper gap by using a gaping tool (available at auto parts stores for under $5, I prefer the "disc" style ones over the wire style) The proper gap can be found in the owners manual and/or on a sticker under the hood
carefully install the new plugs while trying not to let anything touch or hit the electrode on the spark plug (effecting your gap) and tighten with the ratchet and socket, about 1/4 to 1/2 turn pass finger tight. DO NOT OVER TIGHTEN
re-install the boots on the plugs in the same place they came off (this is important, the ran will not run properly if they go in the wrong spot)
YOUR DONE!
