where is the air filter??

[Mikhitar444]

so i just got a 91 Navajo and i'm not sure where the air filter is. i know thats really embarassing but i want to make sure before i go unbolting things that dont need to be. this is my first ford and its a little confusing from having chevy's most of my life.

Should be directly behind the battery. If it's the stock airbox, it'll look like a big plastic hump between the battery and the firewall.

googled this. see the tube that says caution fan? follow it to the left its the box there. has like 4 screw bolts and you can use a flat tip.

Its actually 2 vertical screws and its much easier to take the top off the air box if you take the intake tube (the thing that says caution, fan) off first which is just a single screw/clamp.

yeah i figured thats where it was it just didnt make sense to me that you would have to unscrew it. i never had a car like that before. all the ones i have ever had just kinda pop off. no bolts or anything. ok thanks alot guys

Sort of.. Its got a tube type thing going from the bottom of the airbox to the front of the truck and is between the inner fenderwell and the exhaust manifold. The end is right about the height of the headlight.. just to the inside of the headlight some.

There is also a small tube that from part of that existing tube (airbox to front of truck) to the exhaust manifold. It pulls air from there when it senses its cold out to try to warm up the engine faster.

Its much easier to see/manipulate if you pull the inner fender. Makes getting to the plugs easier too but leaving it out may not be an option depending on the climate you live in.

Here is a shot where you can see the tube going from the lower airbox to the front.

Its missing a vacuum line on the heat riser valve and the hose from the hard plastic to the front got pulled off in this pic but at least you have an idea of what it will look like now.
