I stick with OEM.... I have seen vehicles in the past that run better with the OEM plugs. I hate Champions, but Chrysler products run best with them. I have heard the ecm somehow notices the resistance in the plugs.
The funny part is, I've come across some modern Chrysler's have have NGK plugs from the factory. I've also seen some Hyundai/Kia's that have Champion plugs from the factory.
