Thread: anyone build coil on plug?

My cost on the coils buschur uses is almost $75 each, so after a little math, and time to build the bracket and wire it
$340 is a deal for the buschur part,

Is there any trick in getting it to work? I keep hearing of people that have problems running the C.O.P. setup. I kinda suspect they might be using cheap coils and thats where the problem lies though :roll: .

Well most DSM'ers have problems getting their stock cars to run right so I would not listen to them,

If you can wire a stereo and can read a wiring diagram, you can do it.

dsm'ers have trouble with the COP setup because dsm's are on a waste-spark ignition system.

when you wire up the COP setup, the 1-4, and the 2-3 cylinder's wires are wired together. Since the signal wire gets split into 2 signals, and has to power 2 coils, the spark becomes weaker. If you add an AEM ignition system, the spark will be stronger.

This issue is often resolved by closing your spark plug gap a bit, usually about .024-.026 seems to do the trick for dsm'ers and the COP on stock ignition.
