I don't know why you want iridium plugs. A plug is a plug is a plug for the most part on stock or near stock rides. I just hooked up some spark plugs the other day for my RB20det. But I used the KA24DE plugs. they fit right in. they are a little bit short but not much. I don't know if the part# for the E and DE are the same, but the part # for my Denso plugs is #3130 and they are $1.69 a plug
Edit: The part # for the KA24E for Denso standard plugs is part# 3135 $1.69 at AutoZone

some of the older nissan 4x4's had a four cylinder with 8 spark plugs. but it wasn't a ka24e.
