Accel offers their Super Coil #140061 for the Ford 3.5/3.7 in the Edge, Explorer, etc. The CX-9 is not listed. Does anyone know why? Some aftermarket coils such as the Delphi GN10237 apparently work on both the Mazda and Ford V6s in the CX-9 and the Edge. From this it would seem they are interchangeable. When I change my spark plugs I was thinking about upgrading the coils as there have been several reports of issues. I will try to contact Accel for their comments as well. Thanks!
