I don't know how important it is with modern electronic ignitions, but bad condensers (the giant metal-shelled capacitor connected to the coil) have been known to cause big problems on old points ignition cars when they're missing or wrong sized. I always put a fresh one on with a coil. I've never experienced a mismatch problem myself, but I don't throw out the old one just in case, I just put it in the glove box.

I've done well with Bosch Platinum plugs and with good old AC copper plugs in the AMC engines. In Subarus though, I've gained 3-5 mpg going to NGK plugs. I believe there's some voodoo in plugs where they are matched better to certain engines.

I put the static killer on the antenna and power coming to the radio.

Replacing points with the condenser that came with them was important.

The condenser on the coil actually doesn't do anything for the ignition in points systems. It's the one next to the points that is important. I have used the one on the coil in a pinch when the one next to the points suddenly died though.
