Hard to beat a new set of the ol' AC/Delco 41-602s for our street driven cars.

I hope Bob G or Pete or Marc can chime in here, but for a given set of driving conditons - whatever that may be - the important thing is to establish the proper heat range for the plug. Then, the decision to go with an expensive, rare-earth material plug becomes more of a practical one, driven by how the car is used.

Thoughts?
