I think those are for people with a heavy build that demands that can of spark. Not suggested for a stock replacement, I think I have read people having problems with them for stock use. Anything wrong with your coils now? Stock coils are actually great and last a long time. Also, switching coils will not give you a higher hp at all FYI, same with wires.
OEM coils and wires fit, function and last better than any aftermarket option for your application. I have MSD coilpacks on my Chevy because one of my stock coils failed from a defect in the plating on one of the outputs. They were a great deal when I bought them, only reason they're on there.
This. For these cars you want to stick with AC Delco stuff for everything from the coils through the plugs. Aftermarket stuff tends to work for a short period of time, but often develop irritating misfires that go away when factory components are installed.
Protip: If you don't know what you're doing, don't do it.
