Andygoswick Tune Up for 04 Jeep Wrangler Rocky Mountain Edition Inline 6, Dana 44 front/rear w/ 3.73 gears. Automatic.
Purolator Classic Panel Type Air Filter $14.99
Autolite Xp (Xtreme Performance) Iridium Enhanced Fine Wire Spark Plug-6 ($5.99) $35.94
Castrol ATF + 4 Automatic Transmission Fluid--8 ($6.99) $55.92
Driveworks Automatic Transmission Filter Kit $29.99
Lucas Oil Products SAE 80W-90 Gear Oil--4 ($8.79) $35.16
Permatex Ultra Black Maximum Oil Resistance
RTV Silicone Gasket Maker (3.35 oz) $6.49
$178.49

Here's what I have so far for my tune up and fluid change.. My mechanic is actually going to get the parts at a more discounted rate, but it gave me a benchmark of $ I'm going to need.

How does the list look-forget anything?? (I'm going to do the radiator flush or drain later btw.)

Andygoswick Guess I could have asked what type and how much fluid goes back in the differential of my 2004 Jeep Wrangler Rocky Mountain Edition I-6 Jeep Wrangler.. Dana 44 axles front and rear w/ 3.73 gears.

Lucas Oil Products SAE 80W-90 Gear Oil work?? 4 bottles?

Andy, your 2004 with its distributorless ignition system 4.0L engine is pretty picky about its spark plugs. Older 4.0L engines with distributors weren't very fussy at all. For your engine, there are a number of good choices but three very good well-proven choices include the platinum Autolite APP985 or Champion 7034, or the iridium tipped Autolite XP985. The first two plugs will perform well for about 100k miles, the iridium-tipped XP985 is good for about 200k miles.
Thank you Jerry so much for that information.. Being new to Jeep but working on GMC/Chevy's etc. w/my dad, everything is different and set up different.. Makes sense about the V-6 and I-6-I think those were once called "straight 6?" I maybe wrong but I had a 65 Chevy truck and the pistons were lined up pumping up and down..

As far as the K&N filter is concerned, that makes sense not to use it off road due to the massive amounts of dust etc. so I think I will stick to a good paper filter..

I think my coil packs and boots will be fine and I'll go with the iridium plugs.. I am going to change my differential fluid (thanks for the reminder) and just do a change of filter, gasket if needed, and fluid to transmission.. After that, I think that'll tune up everything I need and get all the fluids to 'start' so to speak..

Thank you so much for all the information.. I actually copy/paste it to a word document and look at the information so I have time to think about what I want to do and how to make my jeep last forever! Lol..

RevCo666 Folks, I'm not here to start a K&N war. Use what you want. I'm happy using my filter.
07-16-2013 11:29 AM
Jerry Bransford All I can say is I personally wouldn't run a K&N no matter what. First, the OE filter has such a huge surface area that in no way could it be considered restrictive. The OE air intake system was designed, really, to be non-restrictive so installing a K&N isn't going to produce more power... so to me, there is no benefit to a K&N on a TJ (though some engines with restrictive air intakes can benefit) while offering reduced filtration. Where a TJ is concerned, I personally only see downsides to running a K&N... no matter where it is driven, especially since I don't believe there are any truly dust-free environments.

I don't even take it off roading, so based on location its safe say that I wouldn't have a fraction of the problems you would have running a K&N(if you did) in your locale
even if this is true, a paper filter flows all the air that is required by our engines. there is no benefit to running a k&n filter. our engines can only pull in so much air and the stock box and paper filter are non restrictive

RevCo666 Another option to look into is changing your differential fluids (assuming its never been changed). Oil change(again if needed).

Just want to throw my 2cents about K&N stock filter(not CAI). I've been using it for about a year in the jeep, I've had no issues (please note I don't drive in dusty/muddy environments or go off-roading much at all) so if you do the same, then go ahead. I think its an environmental issue as to where you go affects the K&N filter functionality.

WredTJ If the radiator had eyes facing the engine:

A V6's pistons would be off set about 80 degrees looking like a V with the crankshaft at the bottom.
A straight 6 (have seen it called both an I6 and L6?) would be a straight line of 6 going back.

Lots of theory and debate and benefits. If yours is a TJ and a 6 cyc it's a 4.0. Newer models are V6 and 3.6/3.8.
07-16-2013 10:39 AM
Ironhead Jed v 6 is set up with the pistons pointing in a v configuration, with an inline 6, the pistons all point straight up and down in a straight line.

we dont have pcv valves, we have crankcase valves, which generally dont need to be changed

and yes, those are coil packs and can only be replaced by purchasing the entire coil rail. there are spark plug boots, but they only need to be replaced if there is cracking

no need for a high performance paper, the standard ac-delco filter works great

Big Sarge I have a question... What's the difference between the V-6 and Inline 6? It's still the 4.0 right??

do not use a k&n air filter. they flow more air do to the fact that they dont filter as much. add the dusty conditions that we see off road and it is a recipe for disaster. they can be beneficial for cars that have restrictive air flow systems, our jeeps do not and you will see zero benefit over the stock paper filter

TUNE UP help..

Ok.. I would like to do an engine "tune up" on my jeep but unlike my GMC, it doesn't seem the same.. With that being said, here's what I thought..

1. New plugs/Plug wires-OEM factory maybe??
2. K&N Air Filter-(ALL my vehicles have one-I love them!)
3. PVC ?
4. Fuel Filter??

What else am I missing that would improve engine durability and keep my TJ running in top shape?? Thanks so much!
