what engine? 1.5 liter typically found in the dx and vx the wires are right in the middle of the valve cover (black aluminum plate on the top of the engine will say sohc Honda in white letters) pull the plugs keep track of what hole they go in use a plug socket and an extension on your socket wrench and remove the old plugs, make sure your gap is the same on the new plugs and insert with the same wrench tighten it a quarter turn past snug. your Honda has an aluminum head so you will damage it if you over tighten be careful. once this process is repeated 4 times return the wires to their respective plug and drive.
