Do not know where spark plugs are located in motor

The spark plugs wires are directly located on top of the engine and the spark plugs are down inside the holes in the valve cover itself. I believe there are also 2 coils on top of the engine, which hide two of the spark plug wires which are attached directly to the underside of each coil, remove the coil pull it upward carefully and you will find the spark plugs for those two in the hole underneath the coil for each one. If you decide to replace the plugs, make sure to check the spark plug gap even if they tell you they are pre-gapped as pre-gapped spark plugs are usually gapped for more than one particular car and it may be incorrectly gapped for your specific vehicle. If you decide to also replace the spark plug wires, you will have to purchase the spark plug wires for the underside of each coil seperately because most local auto parts stores only sell 2 spark plug wires in the set that go onto the non-coil attached wires and plugs, and you have to purchase the coil spark plug wires seperately. So all in all you should have 4 spark plug wires, 2 that attach directly underneath the 2 coils, then 2 regular type wires that run to the other spark plugs. If you look at the valve cover and see the wires, you will see what i am saying better. Just don't forget to ask the autoparts store the spark plug gap recommended for you car, and adjust the gap on the plugs as needed. good luck.
