open engine hood locate distributor(has a bunch 6-8 of plug

wires coming off of it) follow plug wires to the engine remove by

twisting and pulling gently on he boot(thick part) of the wire only

remove 1 plug wire remove the exposed spark plug (with a plug

wrench /socket) under the wire you just removed replace with a new

plug properly gapped & of correct heat range and size for your

specification of vehicle repeat until all are done.
