I beg to differ. Who is stupid enough to buy individual coils at retail or even discount pricing?? You can find brand new Ford OEM Motorcrafts "take offs" for around $50-$100 a set if you bother to look around and call up places. I ran my used coils (not even new take offs) for years and didn't have a single ignition problem. No deterioration, nothing needed replacing, no "cracking" anywhere. In fact, they are the same exact set I will run on my car once I get it back together to fire off a near ~14:1 compression ratio. Go figure.the negatives outweigh the positive with COP's imho. Sure it makes the engine bay look cleaner, but the price of the individual coil is outrageous (for a decent part), and it doesnt take to long for them to start cracking after a few years of enduring the engine bays heating/cooling cycle.
Since this thread is at the top of leader board I'd like to ask some questions.
1.) Do cop coils batch fire.? I'm thinking they don't. Non-batch fire coils better, right?
2.) Cop coils fire higher volts? Short coil wire, or...
3.) How hard would it be to make your own wiring harness?
yes, I wired it into the stock engine harness coming straight from the EEC. I don't have a way of testing the voltage but I'm pretty sure if it was not adequte, most OEMs would not be using them right now. My article can be found in many mustang internet forums by now; I know I've seen it on Corral, Modular Fords, etc. It is simple, and it works.Oh, so it is waste fire. But, it uses the same trigger and module as the stock ignition?
As long as you're not buying the cheap ebay COP then yea, you're going to be replacing them every oil change. But if you spend the extra cash on Motorcraft stuff you're looking at 100K +/- miles for a new set. Same can be said for the coil packs as well.the negatives outweigh the positive with COP's imho. Sure it makes the engine bay look cleaner, but the price of the individual coil is outrageous (for a decent part), and it doesnt take to long for them to start cracking after a few years of enduring the engine bays heating/cooling cycle.
