Doing a tune up. Do I need a new coil?

I bought everything I needed I thought anyway, but now I'm wondering if a coil pack is needed. In a fairly basic tune of my 4.0?

I bought:

Wires
Plugs
PCV valve- While doing that I noticed a gas line was broken so I replaced that.
Fuel filter
MAF cleaner to clean the MAF
Carb cleaner to clean the throttle body.
Air filter also.


I think that's it, but I might be forgetting something. I just figured the coil pack was quite a bit more money and wasn't sure if it was really needed...?

Thanks.

Inspect the case of it. If its cracked or has some odd discoloration it might be bad. Otherwise its probably still good.

Wish I knew that before. Oh well. Thanks for the help guys. I'll check to see if it's cracked or anything.
