Has anybody every fiddled with a coil-on-plug (COP) ignition coil? Cars with COP coils have an ignition coil mounted on every spark plug. The coils are smaller than a standard ignition coil.

<a href="http://www.aftermarketnews.com/default.aspx?type=wm&module=4&id=3&state=DisplayFullText&item=5544">COP ignition de$cription</a> (scroll down to the COP section).

In sets of four, six or eight coils they run $15~$20 each (typical <a href="http://cgi.ebay.com/ebaymotors/NEW-FORD-MOTORCRAFT-COILS-DG486-DG500-SET-OF-6_W0QQitemZ160039578306QQcmdZViewItem">ebay listing</a>). I wonder if you could get a couple for cheap from an auto wrecker?

Might be able to make a much smaller ignition system using a COP coil and a photoflash circuit.

They should work just fine, but they are a little less durble then the oil filled ones that most of us use.

but at $15-$20, its not really gonna save you any money. I got a regular coil from napa for $13, so unless you really need to save every last bit of space it doesnt seem like a good option.

But a regular coils is big and heavy. Heck, a standard coil probably ways as much as the gun it is attached to.

Just looking for somehting a bit smaller and lighter.
