Last weekend, I installed a new Bosch coil from PP and some Clewett wires. This one:
http://www.pelicanparts.com/cgi-bin/smart/...221-119-027-M14 However, the diameter of this coil is too small for the stock mounting bracket. I ended up shimming the bracket with some weatherstripping type stuff for a snug/tight fit. Is that all that can be done for mounting in the stock location? A bummer on the fit/finish, but one thing for sure is that my 2.0L with Pertronix is idling and running much smoother now (per my seat of the pants measurements). The idle is 100% smoother for sure with no "lumpiness". It could be related to the fact that the old spark plug wires were "solid core" and the new are "spiral core". I had read that "solid core" could have EMI issues when run with an electronic ignition. |

The Bosch blue coils are smaller than the original coils and need shimming.
I used to use a piece of the cloth braided vacuum lines sliced in half, always worked great. (IMG:style_emoticons/default/smile.gif) |

When I got a new blue Bosch coil. It came with a new bracket.
It was silver but I painted it black. Used large fender washers. Attached image(s)
