ok i got a real easy q for someone! which coil is the exhaust and which coil is for the intake???

In my experience it does not make a difference. Both coils output the same. The second coil is to help with emissions by improving the flame front. In other words ensuring complete combustion.

oh , my main concern was does one of them fire retarded a little for the exh. plugs?and does it put the same output?

The coils are open circuits, and the distributor closes the circuits at just the right time for each cylinder.

i assume that your red one is intake side? just wonderin...
