Cabin air filter for '94 Dakota

[A.J.]

I had to do a heater core in my shop truck. Since I had to remove the HVAC box, I wanted to build a cabin air filter for it like I did for my mini-van. The inside of the HVAC box wasn't too dirty but I like efficiency and a dirty evaporator core isn't efficient. To do the heater core is 3.6 hours. It took me about six hours to build the frame for the cabin air filter.

The hole for the air box lives underneath the cowl. It was a pain to get in there but not too bad.

Here's the opening. The bolt sticking up is the hold down bolt for the cabin air filter frame.

The frame bolted together. I had to send it to my welder to make the eight piece frame into a two piece frame.

I had to recess the hold down bolt hole for the nut that secures the bolt.

Installed without the filter element. I need to get it welded before I make it. It's too hard to get 12 bolts through the paper compared to 4. I'm going to use a wing nut to hold it down instead of the nut I used in the picture.

Neat Idea, especially where you're at. My first 92 Dak was from AZ, and even living in IL since 98 I was still finding dust in it when I sold it a coupel years ago

I just changed the one in my van. It get pretty nasty. I don't know how long it was in there. This time I dated it.

I had to drill and tap an extra bolt on the long part of the frame. When I tightened it down, it was bowing too much.
