I've been looking at cowl induction for a while. I like the K&N setup (red one) for now. It was $65 altogether and since it's on now I'm selling the AFE to make money towards the cowl setup.

I'll buy your AFE intake if you decide to part with it.

I want to hear more about the cowl intake, can you buy one or do you have to make your own? Does anyone have a link?

i ran the afe on my 99. did i notice a difference? Yea. Was the difference worth the price tag? deffinetally not. Running a Spectre cowl intake on my Comanche right now. worth it? yea. worth the price...yep. is it loud? nope. Kn owing that i can cross a creek without worry of flooding the air box and getting true cold air is all i need. I had bought the New THOR intake for the 99, but never got it installed.

There is a high pressure area created at the windshield/cowl junction when moving. Does your vent pull in hot air rolling off the hood? The vent intake is in your cowl as well.

I have the K&N on my XJ. It was on there when I bought it. I drag raced for years. I don't think you really get that much from running them on stock or mild mod engines. It is nice to have a filter that you can wash and reuse. I will probably sell mine in time and run a snorkel.
I did find a youtube video of the kit I have.

The cowl intake seems like a great idea, I wonder why they aren't more popular than they are, apparently Spectre used to make was as well but it is discontinued. My biggest fear when off road is hydro locking. I have considered a snorkel kit but two things I don't like about it is I think it may restrict airflow due to all the extra piping, and it hangs out where it could be knocked off by a tree limb. Is there any reason not to run a cowl intake? Noise doesn't bother me I am used to driving straight piped 7.3 Powerstroke, has anyone had issues with rain or getting in or it being blocked by snow or leaves?

There is another alternative to the hot air intakes, cold air cowl intakes and snorkels. In the older XJs there is a hole in the bulkhead directly in front of the intake hole in the stock airbox. At least some of them had a tube that ran from that hole to the airbox, providing high pressure, cold air from the grille of the Jeep.

Later XJs have an indentation there, as if it was a punchout that they forgot to punch out at the factory. Seems to me it would be an easy matter to cut out that hole and either get an early XJ cold air tube or make one. Paired with a free flowing drop in filter, I would expect the stock airbox with this setup to perform at least as well as any other solution. The only negative is that it doesn't raise the intake location for water crossings, but in that respect it's no worse than stock.

The base of the windshield is a natural high-pressure area used by a lot of race cars for air intake. Even if you were to get heat from the hood, you get a lot less heat than from under the hood.

Trail Head Off Road (THOR) makes one:

Spectre used to make one, but they discontinued it. However, you can still buy the inline airbox they used and piece it together yourself:

You can go ghetto and build it from PVC from Home Depot, but if you prefer a little more class you can buy silicone intake parts from aptly named Silicone Intakes:

Primarily because people don't like the idea of cutting their firewalls.

Secondarily a lot of people don't like having to oil a reusable filter and wait for it to dry. I solved that problem by buying two filters. One is always oiled, in a plastic bag, ready to go. When I change them, I swap in the clean one, clean and oil the dirty one and then drive around all I want while it's drying. Then I stick it in the bag and put it back on a shelf in the garage for the next time.

Water is a non-issue. I wouldn't do it if you plan to drive it in any dusty conditions.

I have actually considered getting rid of mine. I love the sound of it, but if I park in an area with vegetation that sheds at all, crap goes right down into the cowl and clogs up the filter. I put a prefilter over the firewall hole that helps, but in pollen season it still gets clogged up too quickly.

I may go to the cold air tube with the stock airbox I described above. I'm still on the fence, though, because I really wanted to put a second battery where my airbox used to be.
