Yes,

It is well worth it but I wouldn't buy the packaged deal. I followed this parts list and did it myself.

Its easy, hardest part is figuring out how to mount the TFI coil, luckily I had built my own battery tray and it had a good mounting area for it.

I was definatly able to feel better response in the engine afterwards.

Yes it is worth it. I hade a cross fire problem and idle was rough; I put in this system and solved my problems. You can get everything you need at your local auto parts. The coil alone is about $45.00 get it and donít get the cheap Can type! Buy plug wires for the V8 not the 6 (the 6 comes with what looks like two coil wires).

As far as the wires go, I bought the universal 8mm Accel so I could cut them to length and give it a very custom look.

Juice Box? The system is a distributor cap and coil off a Ford CID engine. Helps with the cross firing problem that the jeep distributor caps are known to have. The cap off the Ford is a lot taller and wider than the stock cap and the ford coil runs hotter as well. I think the term Juice box came from a small company who packaged these few things together and put it out on the market.

i've installed the cap, rotor, and some 8mm plug wires on my engine, and i can already tell the difference. i'm still waiting to install the coil and some platnium plugs.

87 YJ, 4.0 swap, Flowmaster, Pro Comp 4", JKS body lift w/ poly bushings, 33" Trxus M/T, Dana 30 w/ Aussie Locker and 4.10, 8.8 w/ 4.10 and a Trash-Lok, LoD rear bumper/ tire carrier

Thats not an oil leak, it's just marking its territory

Depending on the condition of your current cap, rotor, wires and plugs you may see a huge difference. If all your stuff is already good the difference will be minor, slightly better idle due to the ability to run a wider plug gap and no cross firing above 3000 RPM. The wider gap though will make the acceleration slightly worse, but not hardly noticeable. The Cross firing thing is greatly overated as a problem that this is supposed to cure, unless your really running at high RPMs (which you shouldn't do anyway with this engine) you won't see it, unless of course your stock type cap is bad.
I did it to my Jeep and I think its worth doing if your existing stuff is in questionable shape. You have to make sure you get a good coil though, not one of the $20 units. Your best bet is a Junkyard for the coil and bracket, the stock Ford units were very high quality and seldom went bad, you should be able to get one for under $10.
A really good modification is the Nutter Bypass, it costs pennies and makes a significant difference.
