1998 Nissan Altima Spark Plugs

On the very top of your engine you will see 4 black plugs with wires on them. Those are your spark plug wires. Those go to your distributor cap. Do a full tune up. Plugs, wires, cap, rotor. Very easy job. I suggest while your buying parts, you buy the book on your vehicle as it will give indepth info and pics. If u want to save that 20$ then I suggest you buy a paint stick, and mark your wires from where they come out of the valve cover, and where they go to the distributor cap. Assuming that u have stock wires on it now, they should be marked 1, 2, 3, 4. Also, buy the plugs that the manufacturer recommends, and dont skimp out on money. This is a very important part of your engine.
