I forget CHAMPIO but i do not know which type should i use, in my car there was two types of Chamipon sparks, and i am not quite sure which ones are correct. As to our shops when i mention Dodge Challenger i only see big round eyes and nobody knows what to offer, additionally the catalogues they have quite ofen are diferent so even when i mention part number they still do not know anything, such a nice place ( as was with KYB shock absorbers, wehen i mentioned part number from american catalogue answer was always it is a wrong number)
