I have decided to add an onboard air system to my 1997 TJ with a 4.0. After much consideration, have decided to use the ORO kit. I understand that the compressor may be a bit smaller than others have used but I feel it will be right for me and my needs plus it allows the continued use of the stock air box (Edit - ORO has updated their description and it does not work with the stock air box) and does not appear to need a coalescing filter (unsure in this part).

The kit comes with a length of steel braided line to deal with the hot air coming out of the compressor that I will use to take it to a manifold. From there, I will:

(A) Run a line to each side of the Jeep to couplers on the frame below the doors to allow a short hose to be used to fill tires and blow out the interior. In this scenario would it be best to run one line back to the passenger side (same side as compressor), split it and run it across to the drivers side or run one line from the passenger side and one line across the firewall and the down then driver side frame?​
​
It seems that going down each frame rail would allow the hose to be more firmly secured vs crossing under the frame but I would like to hear / see what others have done.​
​
OR​
​
(B) Simply run one line down the passenger side frame rail and one to the front bumper. To me this is less than ideal for two reason (1) it is not tucked away and out of sight (2) Not a deal breaker but would need a longer airline to inflate tires / blow out interior.​
​
OR​
​
(C) Some great line routing suggestion that comes out if this thread.​
​
Thoughts? Pictures?

You will need one. You can put a set screw in one of the oil passages safely to mitigate oil spray, but it still is pretty spitty. The speed of it is nice, but I'm not convinced my York was worth the money.
 
I used the kit as it came but added an oil catch to mine since it was spitting some oil. From there I ran a hose down to the bumper to make a remote fill location.

I am beyond the evaluation phase, but yes I have thought about a co2 tank and have run one for years. It is about to find its way to the classified section of this forum.

Too bad you're not close, I'd consider a swap for the right deal.

Thanks for the input on the coalescing filter. The ORO website described “The York compressors we currently offer have proven to not only be reliable but also shown to introduce so little oil into the air system that we have decided to reinvent the package.” and since the kit does not come with a coalescing filter, I assumed it didn’t need one.

As I said above I have the same kit and wanted the filter. Others around me have the same kit and dont need to run it. I'd say hook it up and see what you're working with before buying the filter.

For what it's worth I'm happy I went with the york over co2. Having unlimited air and not having to think about how much air I have was a major factor in my decision. 1 min a tire from 6ish to 25 is plenty fast for me. Especially since I'm typically filling others tires after I'm done since they're using much slower systems.

Despite the original product description on their website of being able to maintain your stock air intake upon further questioning i was informed it is not possible. I think I may abandon this project for that reason.

It is my understanding (maybe incorrect) that if you modify the intake you run the risk of failing visual portion of the Ca smog check. Have any of you Californians experienced that?

I had a stock air box with the york. It wasn't until i moved to highlines that I chose to swap it out. The k&n intake I have now is carb approved and I have no risk of failing for that reason.

A/C is on the passenger side in my 1997. The kit I was looking at adds a second compressor between the existing A/Cand the airbox allowing you to have both OBA and A/C.

Thanks for the information on the K&N. I have read conflicting information which is why I am here for real-world experiences with smog checks. Some have said that only a carb number is important other has said that a particular carb number has to be approved for your vehicle specifically implying things like no Windstar intake on a TK.

All that ca cares about is the carb sticker.

CA requires a visual check of the vehicle during the smog test and if anything important like the air intake, catalytic converters, etc. are aftermarket it will fail the visual unless the aftermarket part, like a CAI system with a K&N air filter, has a valid CARB sticker.

Which is just one reason I bailed out of California this past May. And K&N air filters pass so much dirt, fine dust, and silica that I stopped using a K&N 20 years ago.

Any aftermarket part that replaces or modifies an emissions control component needs a C.A.R.B. EO number for the specific part designed and registered for use on a specific Year/Make/Model. Homebrew intakes like the Windstar are illegal.

I also run a York I installed an outlet just under the headlight and a second just on the inside the rear driver side near the roll bar. I also added an inlet filter on the passenger side and then after adding my OBS I relocated it my drilling a hole in the engine air box so that filter is doing double duty

You could get by with only one outlet but having one at each end works will to inflate your friends tires as they will line up once they see how much air the York puts out compared to there little plug in compressors
I also use it with a air gun to inflate air beds, rafts, etc. just carry a air hose and attachments

Late to the show and not much to add regarding the ORO setup (I run an ARB and it works a charm). I will offer that I ordered some parts from ORO around holiday time and have trying to get them since April. Their voice mail says they are away at a Jeep even and they haven’t responded to emails. Might have changed in the recent weeks.. not sure. I gave up trying to reach them.
