Stock NGK plugs are the best plugs. As you raise the boost of the TT model, you can opt for the colder grade plugs but still stick with NGK.
Remove the coil pack for each spark plug, then reach inside the hole with a ratchet extension and unscrew them.

There are two plugs on the 300zx manual transmission. on on the passenger side and one on the bottom of the transmission. You can unscrew them with a 1/2 drive ratched. fill through the plug on the side, drain from the plug on the bottom
There are several things that can cause your 1993 Nissan 300 to idle rough. The most common cause is dirty spark plugs. Bad spark plug wires can also cause the problem.
