I have a 99 gtp with the following mods, 1.9 roller rockers ported and polished heads, ported and polished blower, 3.5 inch downpipe with cat delete, 3.1 undersize pulley, tune by ZZ performance for 93 octane with kr, its my first time changing the plugs with the mods, and I don't think stock would come gapped right any suggestions on how to tell what the gap should be?
 


Iridiums are fine if you don't want to change them to often as opposed to copper where you'll be changing them every 2-3 oil changes.
 




Ok, so just the same as regular, not trying to insult you, just thought there might be something special you had to do, either plug I choose the general consensus seems to be to run around a .50 gap for my setup right?

Just if you need to open the gap use pliers as not to damage the tip thing, .50 is what iv been told and seen
