TJ Cabin Filter

Hi everyone and thanks for your comments. I do not have the part number but all you need to do is after removing the cowl and air box, measure the opening then go to Tractor Supply and purchase an air filter that is close to the measurements. I had to trim some from the edges then duct tape.
not installed yet but here's one i picked up today mated up to the old plastic lip from another cowl.
Filter is backwards. Not sure how much that matters for flow. Obviously mounting is easier that way.
The engine has a similar filter (bigger) but the way he has it mounted looks correct for air flow.
On the engine the open pleated side is down and the air flows up thru it to the intake. Using gravity to help shake / drop debris out.
that's a good point. honestly hadn't put that much thought into it. I figure It will get filtered either direction.
Ten dollar filter and some duct tape to keep the wife's sensitivities in check on our next trip seems well worth it lol.
I posted it so others who have asked for a part number could have somewhere to start.
Glad to see someone try this, I was thinking of building something similar after my last wheeling trip. Being in the back of the line on a dusty road sure does suck up all the dust, and was thinking... The only way into the cabin airbox is through the cowl correct? Because I was thinking of building something that can hold a filter underneath where the vent/meshes are on our windshield cowl. Only thing I have not considered is what will happen if it gets wet?
What happens when it rains and water runs down the windshield ?
maybe not the best mod for seattle. haven't had a good rain here in over a year... hence the need for a cabin filter.
fixed it. just take it off when it rains. now everyone can benefit.
My reply was to the previous post that said it was mounted the wrong way. The air flows downward thru the HVAC ducts. You pictured it correctly mounted for airflow.
a poor attempt on my part to address two posts while only quoting one. I understood your post (which is correct).
well hold on now, there may be different designs to divert water underneath the cowell as i found out today. This looks nothing like my last Jeep. much better design but without chucking it this filter wont work here.
So i wasted ten dollars on a filter.
Without the plastic contraption it is a tight squeeze on one end but with a little trimming of the edge it would work.
just be aware of what your up against before commiting to this.
Yes, that is the newer style HVAC intake. I think I mentioned that a few posts back. Gonna have to get creative with that one!
I measured the opening and used an air filter from tractor supply. I had to make some minor mods but it fit.
Another alternative is to pop out the dashboard center bezel and clip some filter material to the back of the vents with binder clips. It prevents that cloud of dust when turning on the A/C, but isn't so tight a weave that it overworks the blower motor trying to flow air.
I use household heater register filters. I usually have a couple left over when I change the filters in the house which are perfect for this purpose. One downside is that they don't filter dust as well as a pleated cabin air filter, but the upside is that vent filters are cheap, one doesn't have to remove the cowl, and there is little or no risk of moisture damage.
The register filter can be seen in this photo - the white material behind the vents.
