I think a lot of people call something like an LS coil "coil on plug" where it is really "coil near plug". There is lots of really hot factory coils out there on all kinds of cars. You might search around on the forums at MSEXTRA.COM and see what people say about those RX8 coils. That is the megasquirt support forum and it is global so there is a very wide range of vehicles and unique setups there.
