if you are modded go with autolite copper plugs of the appropriate heat range
if you are sock another set of the stock plugs will do just fine and last alot longer
Well...is your car stock?
If so...Autolite 606's gapped at .055".
for a GTP you want autolites...simple as that
iridium is fine for an engine that takes well to those plugs.
These ones love copper plugs for some reason.
