If you have 2002 Excursion, you should already have a trans temp sensor and gauge.

The "idiot gauge" on the dash for trans temp, and the OBD accessible actual temp via Torque Pro or similar monitor.

You can still add on a sensor and gauge if you like. Up to you

 

If your using the AIS intake make sure you use the sleeve threw the fender as well. I think the S&B would be a better option but I do like the AIS as well. Also it mitt smoke a little down low still you up grade the turbo. Need that air. Your on your way, it will be a hole new truck when your done. Do what Stewart showed you, My trans runs really cool with that cooler.

 

Yea I'm adding gauge and sensor. Stock sensor in my excursion hasn't been to accurate. Never been over 220 deg but yet I'm on my 3rd transmission.

 

I was considering doing the zoodad mod for my AIS like I did for my excursion. Is the fender intake better?

I'm done with washable filters. I've hated my afe since I got it. As much as I drive id rather buy disposable filters. That's why the AIS caught my eye.

 

You want the 6637 filter setup then.

Riffraff Diesel 6637 Ford 7.3L Powerstroke Intake Filter Kit

I too have the AFE filter on my Excursion. It's the AFE Stage 2. And compared the 6637 I have on my F250? I'd rather have the 6637, hands down.

Whenever you feel like the 6637 is dirty, you swap it for a new one.

The only reason I haven't switched the Ex over is because I still have cleaner and oil left for the AFE and i'm too broke not to get the full return on my investment.

If using that kit then all I see happening is super hot engine air going into the intake. Isn't the whole point of a aftermarket upgraded intake to get less restriction and cooler air into the engine?

 

Once a rig gets moving, the air intake temp is within a few degrees of ambient.

Stewart

 

Disagree and agree. I have the 6637 and am happy. My underhood temps are higher than i expected at the AIT sensor next to filter. The air temp into the filter has little to do with the temp of the air entering the engine due to the intercooler. The air going into the engine (MAT sensor reading) is within 10 degrees of ambient. only time MAT climbs drasticly is when i park the truck and shut it off or if I am out of the turbos efficient working range.

I see no problem with my setup. would cooler be better? Sure probably but MAT is important not AIT.

Edited to make more sense.

 

The OE sensor in the trans is fine, it's the dash gauge that sucks. It will only show hot when the trans is already taking damage. I had that happen while towing when I first got the truck; I pulled over as soon as it showed hot, but by then the fluid was already burnt and brown with glittery bits of 4R100 suspended in it. Luckily I caught it early and with a fluid and filter change (and a valve body and 6.0 cooler ftw!) the trans has been fine for another 40k. The temp sensor in the trans also sends data to the PCM, so you can see it on your Aerotech gauge.

If your 6.0 style trans cooler suffered thru one of the trans failures, it is likely to have debris in it that will continue to kill the next transmission. It is very hard to clean that type of cooler. The conventional wisdom is don't bother to try. Get a new one because failure is too expensive.

Let you tuner know you have the JW valve body so they can factor that in, otherwise shifts can be pretty harsh.

Definitely sleeve the AIS due to the big injectors.

 

I can only post the results I got, as best as I can remember. And while the test was less than scientific, and it was done almost 20 years ago, IIRC the significant difference in temps only occurred when moving slower than 20mph.

I'm a fairly simple guy and am far from an engineer or scientist, but if that were true, we wouldn't be talking about the heat of the engine affecting the temp before it enters the engine, or am I confused? (Standard SOP for me, LOL)

The ambient temp and the conditions being driven will affect the temp of the air entering the filter and that temp does matter.

The point I was making was, once moving near city driving speed, the heat generated underhood only affects the air temp entering the filter slightly (subjective definition/term) and isn't a concern, in my opinion.

Stewart

 

Yes, both sleeve and front intake on the AIS.

 

I've purchased the AIS system for both of my trucks already. The second I saw the description for upgraded intake with disposable filters I was sold instantly. So 6637 is out of the question with both intakes sitting in my shop waiting to get installed. Not saying the 6637 is bad, but it looks like one of those DIY filters the ricers run. I like the factory look of the AIS.

 

My work trucks 6637 looks and fits perfect, I don't know why everybody's 6637 is just dangling in the engine bay

Dirty engine bay but looks better than most I've seen

 

I would like cooler temps for the incoming air. may need to build a enclosure for the filter and test.

poor blurry picture. I may have something funny going on not sure. Driving to work pulling the toyhauler 60mph up a little hill in OD (left it in 4th after this) about 68 degrees ambient -------- 113 underhood IAT behind filter --------- 86 MAT after intercooler

 

"up a little hill in OD (left it in 4th after this)"
Just an FYI forth IS overdrive. Therefore the designation of "4"R100.
