Check out autozone.com for a free repair guide. Should purchase a more detailed repair and maintenance manual.

All you need are the plugs and wires. Remove one wire and plug at a time so you do not get wires crossed and cause a misfire. Buy a cheap plug gapper and gap the plugs to approximately .060 inch. Tighten the plugs to about 25 ft. lbs. of torque and be on your way. You may want to change the air and fuel filters also.
