Can anyone tell me or tell me where to find out about the differences in the Excellerator coils for the Explorers. I have seen three and all were different. First one was oddly shaped and did not appear to be molded well. Have two more which look the same from the top but one is thicker and has smooth sides where the other is dimpled. Any info on the age of these and how well they work is greatly appreciated. thanks Steve i
