Hi all, I am looking for you opinions on aftermarket Coil on Plugs. From what I have read, everyone seems to split on the aftermarket vs. factory COPs in this particular case. I understand that the stock COPs can support 800+ horsepower, and that they'll do it just fine, but does that...

we all know they come 320 from the factory but with drivetrain loss in the 270-280 range i dont find that too fitting knowing my cobra is under 300 if dyno'd i do like too have fun with my car of course and maybe a few runs here and there, i want my cobra to basically have the real rating my car...
