Default MSD offroad ignition

I have a msd ignition sitting in my closet. I bought it about 3 years ago for another truck, but I never put it on. My question is should I bother to put it on my Jeep? I have read that the Cherokees have hot ignitions already, so would I even get any benefits from it?

Of course I have all ready put msd wires and a coil on it, along with new plugs and distributer cap and rotor button. I want to know if I will get any more benefits from the ignition?

If you are talking about a CD box like an MSD 6a then yes it will help. The multi-spark under 2k rpm is nice for torque and helps with throttle response. You may get better mileage but not a 'gar-on-tee"."

Should work nicely then. Good luck with the install, its pretty easy but if you have any questions feel free to PM me.

Curious to see how you wire it up. If you take any pictures let me know.

I put a MSD streetfire cd box on my 91 xj. I love it it was cheap like 200 bucks and it has a 100 incerment rev limiter built in. Noticed a little difference in my throttle response and the rev limiter works great for long areas with mud. (since older xj's dont have one)
