Air Box Help

Hubie151 · May 15, 2009

All you guys running an MIT tube and aftermarket filter, do you order the aftermarket filter to fit the stock air box, or is the stock air box removed in this setup? If so, how do you ask a competing company what filter will fill the other brands MIT tube lol. I ask because I would like to go with the Airaid MIT tube (cheapest I have found), and a K&N filter, always had good luck with them. Thanks guys.

Filter to fit the stock box

wmorgan518 · May 15, 2009

I found a stock replacement Fram Airhog filter on Amazon for 15 shipped, pretty good deal, will be using that with the MIT i found on e-bay.

All you need is the K&n Drop in filter. Works fine with the tube.

So im guessing that the main restriction as stock is in the tube then? Do the cone shaped K&N filter's flow better than the square flat shaped K&N's?

I kept the stock box on my truck but dropped in a K&N filter. I drilled 3, 2" hols in the side of the box; 2 facing the passenger side, 1 facing the front bumper BELOW the filter to help with air consumption. Works great.

Airaid MIT, Airaid filter, cut out the front corner of the stock box

took out the box, and dropped a cone in, enlarged the hole and extended it so its a bit in the inner fender.

Any of the cone shapped filters will not fit inside the stock box with the stock tube because of the angle and the setup with the gear clamps and screen filter inside the stock tube, how'd you guys (with this type of mod) get arround this? thanks.

Actually, a better question would be is anyone using the stock air box with a K&N cone filter? And if so, what is the part number? I will be adding a Airaid MIT tube as soon as its in this week.

A cone air filter will not work in the stock air box without serious modification...You'll have to cut the tray up and then put some kind of adapter to mount the cone to the MAF. The stock air filter is a panel type and that's actually better I would believe for filtration...

I just put the Airaid MIT on my truck today but my damn AEM filter is backordered...

on the K&N box, it says that the cone filters flow much more though, i guess I dont have an option though really if I want to keep the stock air box. I noticed that K&N have many filters with different angles on them, I wonder if one of them fit.

Ranger · May 17, 2009

K&N does make a panel filter that would drop right in...But the mainly issue to switching to a cone or whatever angle filter is the stock intake is designed to drop in flat, and the cone filters have to actually slide into the MAF and I don't believe the stock intake is set up for that...That is, there's nothing for a filter to slide onto which means you'd have to get or make an adapter so the filter stays up to the MAF...I don't remember what the stock intake looks like inside but I can guarantee it's flat around the hole going to the MAF.

i had a k&n drop in in my truck. then i did the whole k&n intake

Yeah, I would say the restriction is in the tube and the giant silencer chambers on the stock setup. The stock air box is already a "cold air" design...
