AEM cold air intake

CRDburnouts · **Posted:** Tue Nov 28, 2006 2:11 pm

So this company that I bought my muffler and chip from told me that they would either give me a free K&N or below cost on this AEM cold air intake system(oil-less); that is if I take a couple photos of the stuff and write a paragraph about how much it's helped and how easy it was to install.

The question I have is should I just get the free K&N and sell it or is this intake worth getting? It would probably run me around $180 and I dont want to regret getting it. As far as I know cold air is not a reason to void your warranty, correct me if i'm wrong.

I'm planning on buying one of those. I might switch to a true flow foam filter for better filtration, but I think it would definitely help. Let me know if you don't want it, I'll take it off your hands!

I am running the AEM dry flow on my Powerstroke (want to get one for the KJ too).
I picked up a little milage over the AFE oiled filter I was running. I have been very happy with it and it is much easier to clean, which means I clean it more often!!!!
It other thing I like about it being dry, is sort of self cleaning to a small degree. The larger particles are knocked off when you hit a bump, rather then clinging to the oil....

Since the mass airflow sensor mounts in the lid of the airbox, where exactly will it mount on the AEM intake?

Also of concern to me is how the filter is sealed off from the engine compartment. If you were to install a thermocouple in the airbox of the KJ and monitor it closely when it's hot outside and/or trailer towing (heavy load on vehicle), you will notice that the incoming air temps will rise sometimes 40-60 degF over the ambient due to the mechanical fan engaging and the hot air recirculating in the engine compartment. If the AEM intake is simply loose in the engine compartment and mounted where the airbox used to be, I can see this as being a bad idea for a number of reasons. First will be the definite increase in intake air temps with the delta over ambient being upwards of 80 degF. If the air going into the turbo is already getting overheated, the air coming out of the turbo compressor will be even hotter which isn't good for the turbo seals which already leak oil. That will also result in an increase in intake air temps (post-CAC) which is not good as well for combustion. Additionally, there is an algorithm in the ECU software to derate the engine for protection purposes if the IATs get too high. It will dial back the boost and cut back injected fuel quantity to manage the temps which of course will result in a real hit in power on a hot day.

Good insight into the potential problems, I am not sure about any of those issue that you brought up. If I use it I will probably try to isolate it in the stock airbox location with some plastic or something to keep the ambient air temp down at the filter.

Has anyone alse noticed how that hole in the grill allows air to flow almost directly into the air box? (with that plastic peice removed) There's a good source of fresh air if you done have fog lamps.

You are observant and stumbled onto another Liberty CRD design issue which is in another thread. That plastic cover (which is blocking what would be a very effective ram-air) is supposed to create a right angle in the air flow to keep rain water out of the air intake. The issue is it doesn't work. The CRD is a very effective wet-vac, pulling anything in front of the grill through that opening straight to the air filter element including rain water. If you haven't already, read the "wet air filter" thread. It's a long one, skim in through the first 4-5 pages.

The water problem is easly elimanated with install of lower section of '02 3.7L airbox with the intake snorkle and water deflector.

The add in the link says:

"Stainless-steel heat shield included " ??????

I wonder what it looks like. :?:

They will sell it to me for $180, should I go for it? I believe they are giving it to me slightly below cost but who knows...

Go for it. The cheapest I could find it was $240. Any chance they could hook me up with that price as well? I would go for it at that price.

Anyone get thiers yet? Anxious to know how the sensors hook up to the new airbox.

I really want to get one of these but don't want to be the guinea pig.

elysium · **Posted:** Wed Dec 27, 2006 6:06 am

If I could get it for 180 I would jump on it right away. I remember someone ordering this intake before and another person's CRD was used as a prototype for the intake so input would be very much appreciated.

Anybody get one yet? If so, how did the install go? Pics?

You're just as anxious as I am!

I put an AEM in my V6 Liberty several years ago. The stainless steel heat shield was a large baffle plated that bolted to existing holes in the engine bay, while the aluminum tube connected to the throttle body via a rubber bushing. The heat shield is only a single vertical separator, not an enclosed system. Not sure if the diesel version is different.

Throttle response improved but noise level went up too. I reused the old V6 factory airbox for the CRD to get rid of the water/dirt problems.

What I am curious about is where/how the MAF sensor will connect up to this setup.

These guys have the kit for $240. I am hoping some of the noise goes up...specifically I want to hear turbo sound....but without putting a whistle type device in my exhaust pipe :lol:

It's right there in the picture - look just past the air filter and look at the right angle connector coming out of the air tube. You'll have to pull your old MAF and install it there and connect the sensor plug to that connector. Unless AEM can produce some dyno graphs showing significant power increases, I don't know if it would help too much, especially without hot engine air isolation. The V6 airbox mod puts the intake right at the outside hood seam that would probably provide more cool air than any inside tube design.
