I just got a red top s13 motor into my 95 240sx and i wanted to give it a tune up. I want to know what part number is the OEM sparkplugs and who makes them? Also what else should i replace as part of the tune up?

Thanks

i used NGK iridium BRK7-EIX11 and gapped them to .29

 

But doesn't anyone use the stock sparkplugs, also can I get the plugs from a nissan dealer if i have the parts number? Also what kind of sparkplug wires are good? And where can i get them?
