So who knows if he's talking out his rear, or is uninformed, or is right



Originally, waste fire ignition engines had two different plugs.
One side of the coils had normal platinums, and the other side had "reverse" platinums.
This has been superceded by using double platinums on both sides.
This is not a mystery and is definately true.

The reason the original plugs were both normal and reversed platinums is they are cheaper.
$1 a plug, times four cylinders, times a million cars - is four million dollars saved.



Sorry, I didn't get what you were saying, you sound like you have some knowledge of this so I'd like to comprehend what you're talking about. What is a 'waste fire ignition' ? Are you talking about a head that runs 2 plugs per cylinder ? My parts guy did say that sometimes the dual plug heads would run different plugs. But the previous poster said the #1 and #2 plugs were different from the #3 and #4 plugs. The numbers were identical with the exception of an E at the very end of the ID number.
