On my last 2.6's, I used an Accel yellow SuperCoil, and it worked just fine, for about 150kmiles. I'm very fond of NGK plugs and wires, plain vanilla plugs work just fine. I've had problems with the unobtanium plugs. The center electrodes are very fragile. I had a glass bead blaster plug cleaner, and I'd pull mine and clean them up and regap about every 5k miles. I've used taylor wires in the past, the common vanilla kind, and they were decent wires, but not as good and reliable as NGK's. I had bad luck with Magnecors, fragile connectors, mostly...

On the accel coil, I bypassed the resistor and wired both the on in start and on in run to the coil +. You take the wire off the bottom of the resistor and move it to the + post. I found I had a much more stable idle and no spark fade at above 5k rpms.
