Jacobs Omni Magnum
s60, I've had the system for over three years. It gives you what they claim and more. One advantage over the MSD,or any other cap/discharge unit, should the Jacobs fail, you simply exchange the J coil wire for the original and you're running again. You should obtain thier Tech Sheet for all the info you're seeking. Spark Plugs, Champion Copper core, gap 0.054 inch. Plug wires, Jacob 8mm silicone. When you put all of the mods together, the old tub does quit well and I still get 27-29 mpg with A/C at 70+ mph. It works for me. Happy Trails Beep Beep from Houston.
