1st put your car mods and year in your signature so we know what car you have but to answer your question get autolite #25

autolite or ngk. For autolite #25 for copper core, AP25 for single plat and APP for double plat. If your mods are extensive like heads/cam or nitrous or blower you need a reduced heat range..for autolites, that would be the last digit ....so 24 would be one heat range lower and so on. Platinum isn't recommended for nitrous due to excess heat removing the platinum plating but suppposedly iridium plugs are ok and of course the standard copper core plug....#25 is ok.

you dont need to be liek a ricer and list your mods in the sig. if ppl had to list there mods in their sigs there truly wouldnt be enough room for all of them
