cab air filter install (pic)

So following Stu's friend's idea i thought i'd add one myself, because i'm sick of cleaning the jeep after every drive on dusty logging roads....


I wasn't about to spend money on a KN&N nor do anything fancy, so this is what i did ....

I took measurements of the hole and went to my local Canadian Tire. I bought a Motormaster filter for $8 (CAD) that seemed to fit the dimensions. (The green stuff is filter material for a furnace. The hole "tapers" to one side, and causes the fins of the filter to bunch up, creating a gap, so i filled that with this stuff)

This filter fits perfectly, the fan blows nicely, but it got me thinking .... would a filter like this put too much stress on the fan as it sucks air through???? anyone know

what do you have holding the filter down? Looks like it would come off with a few good bumps

It is a very tight fit, but i have put a strip of duct tape around it, mainly to close any "gaps" where dirty air could leak through...


The rain stopped so i went outside to run the fan at full blast and i answered my own question about the filter "stressing" the fan..... at full blast the fan sucked my hand to the filter easily, it could probably draw air through 5 of these

It is on the passenger side, right under the cowl.

don't have any photos of the cowl, but it's the "grill" right below your windshield wipers. you can remove that part....

you can see it here on stu's website

http://www.stu-offroad.com/body/cleanair/cleanair-1.htm

there you can see the rectangular hole where your fan draws air, and dust as well

Will that filter just sop up water when it rains and water goes down into the cowl through the center vent?

That's good.
I might just get some foam, but I was also thinking of looking for a filter that would just about fit ... there are lots of sizes to choose from.

Shouldn't be a problem with the stress. I hope not. The cabin air filter for the WJs you can buy basically does the same thing. Great idea I might have to do what you did myself, but yes tell us if it does leak.

how can this possibly be any worse then the naked exposed hole that's been there for 10 years?

Also, when water goes into the cowl, it will run through the slot at the bottom, down behind he engine

Maybe i didn't understand your question

Well, I guess I'm thinking that with just the hole there would be some drain holes down there so the water drains before reaching the fan. With the filter, it it gets wet it will hold the water and you will have a humidifier instead of a hvac system...

I like this idea but I have never looked under my cowl so I don't know whats really goin on down there. Will the filter get soaked or is it protected from water through the vent in the cowl?

The "drain slot" in the cowl is the lowest point, any water that gets in there SHOULD drain out the bottom

on top of that, the filter is raised about 1" above any of the metal surfaces, so if any water gets in the cowl from the sides, it will likely go around the filter

so hopefully it will stay dry, but we have yet to see. Now you ahve me thinking though .... because the write up on Stus site uses a Kn&N filter taht's located AWAY from the fan hole, closer to the cowl opening where water could get on it (then again maybe he lives where they have no rain)

you can see the raised "lip" in this photo, on top of which the filter sits

Time for a Revive lol

has anyone tried to put more slots in the cowl to facilitate more air available for the cabin air intake and also possibly easier to plumb engine air availability ?
