Intruder, we were wondering if you got bet better performance, especially accelleration with your ignition upgrade. Let us know. Someone recently posted about a coil uopgrade on a 300SEC maybe the answer for him.

I never measured it but the car felt stronger above 4000 rpms and gas mileage went up about 10% for both city and highway driving. Hope that helps a little.

P.S. One thing to note. You MUST use plain old copper spark plugs with a slightly wider gap; any thing else is a waste of money and is counter-productive to the high energy coil, especially fine wire electrodes which were originally designed to make up for an aging (weakening) ignition system. If I could find some surface gap style plugs(a.k.a. oil-burning plugs) to fit I'd use them.

I have been using the Jacob's Omni Magnum for about three years, and it does as advertised.
I use thier 8mm plug wires with copper cored plugs gapped at 0.051 inches.
I tried the MDSI capacitor dis-charge unite and couldn't realise any improvement and returned it.
I can relate to the 4000 rpm feel.
It feels as if it is 5 cycling as we used to say in my younger hot rod years; getting on the CAM.
I'm using OEM coil, if you know what coil improves what is already super let us know.
