I have used the 6AL in just about every car I've owned, it makes a real improvement in performance, it also has a rev limit that you can change with little modules that plug in.

I use the DIS-4 in my '97GT. It has a 2 stage Rev limit, it can also be programmed to retard the timing at a specific rate and rpm, for use with Nitros and such, or cheap fuel in my case. It also comes with an anti-theft thing, that you can wire to a switch, so the car wont start.

Both ignitions increase spark energy, and spark multiple times for 20percent of crankshaft rotation to completely burn off all the fuel.

I'm not positive, but i dont think you can use the 6AL on your Cobra anyway. The 6AL is for engines that use distributors.
