Best plugs, wires, ect. for a 5.9 tune up?

Looking for some advice from some five-niners. I see lots of options when it comes to wires and plugs, looking to see what has worked well for you guys. Part numbers would be a plus. Thanks.

I went with a kit from CRT performance. I havent installed it yet but it includes 8mm wires,cap with brass studs, brass tip rotor, and a 45k coil. All made in the USA. It cost about 100$.

Also interested in knowing which one, that sounds like a pretty good deal. That's without spark plugs right?

Yeah I've heard about Kolaks kit but couldn't find it when I searched the forums. I'll email him and get more info, thanks.

From Kolak:

I've always used Autolite platinum plugs in my Kolak Ignition Upgrade kit. Here's all the information - JeepForum members get 10% off the below pricing:

My recommendations for the 5.2/5.9 ZJ ignition system are designed to improve idle quality and throttle response, and to improve and maximize current transfer. This really helps support other modifications. Here's what I recommend:

Magnecor KV85 ignition wires
MSD high output replacement coil
Coil adapter pigtail harness for '98 Jeep
Heavy duty US made brass terminal distributor cap with rotor
Autolite platinum plugs (one heat range colder than stock)
You still have to PM him for pricing. If you want the best, though, his package is hard to beat.

So is the consensus on plugs the autolite 3923 ? Sounds like alot of people are running them with the hotter coils. Any input?

Kolak's kit is supposedly the best (hey I bought it), but you can do a decent tune up for much cheaper.
