Coil on Plug Information

Sendero · 02-15-2005, 12:23 PM

How do they work? (I know the theory)
Each of those eight COP's is an individual charging coil correct?
99+ DOHC's that use them fire individually rather than in pairs? (in that they don't use the "wasted spark" of the 96-98 Cobras)
Anyone have a "used" one that I could have?
Anyone have a "used" COP harness from a 99+ vehicle I could have?

Any pictures, websites, or information would be greatly appreciated!

Coil on plugs aren't gonna give you any better performance and they do tend to go out sometimes intermittently which is a pain to troubleshoot and they are like $70-$80 a piece when you have to replace them.

They work the same as with any coil ignition system. Except instead of firing 1 coil 4 times, in your case, you are firing each of 4 coils once. Still uses the same crank sensor as a trigger. Technically you should have less heat in the coil since a smaller coil has less mass to retain heat and also fires less.

Just the part with the COP plugs if you don't mind. (Which connects back to the EEC)

Thats what I meant. Is there a plug that it goes into? Or was it a wire job?

How much you want?

It was off the 01 4V harness that I hacked up for my 4V swap. I need to get over to my storage place and dig it up and I'll ship it out. Just pay for shipping.....I'll let you know when I actually have it (that pic was in my files)...
