spark plugs

[90CivicEx]

ngk rates thiers backwards anyways. 7 is thier cold plug, haha!!

see when i worked in the parts store every plug i delt with the higher the number the hotter the plug. I never delt with ngk's unless i bought em but never really needed a colder spark being that i wasnt turbo'd. Also please believe i live in a redneck town so its all chevys and fords around here lol.
