Default Chapion Plugs 7570 or 7440?
Advanced Auto & Rock Auto list #7570 Double Plat as the correct plug for a PT. The 7440 Double Plat still exists which some people on the forum say is the correct plug. Who's right? Proper gap..040 or ...050? 31K on car I heard the OEM wires are junk should I replace them...car runs fine.

Thx, 66CUDA
