"I have a 1997 Ford F-150 4.6 Liter engine, I would like to know that will some of yall MSD Ignition Coils work good with stock ignition system without any major changes having to be made, I read that they will work good with stock ignition as well with MSD ignition 6AL boxes. I have new ignition wires by Duralast and new Autolite Double Platinum Spark Plugs. I see that these coils will put out a stronger output and smooth idle and improve mid range RPM power." the part #8241 is the coils and the 35279 is the plug wires that will fit on my truck. All I want is a upgrade, I do not wanna have to add no new ignition box and adapters, I just wanna add new color, as well as the options that those coils will do, especially fuel efficiency, throttle response, smooth out idle, and more, all except high performance
