I still have three factory air filters sitting in my garage that I want to use, but I was thinking that once I used them up I would switch to a BHAF in order to get some more air to my truck.

I know a few folks have installed them on the 3rd Gen trucks. So, I have some questions.

1) What parts were necessary for the install?

2) Does the hose going to the turbo connect directly to the BHAF or do you have to make modifications?

3) Which BHAF is a good one to buy and about what do they cost?

4) I saw someone here who had some kind of outer cover over their BHAF. It seems to me that this would be a good idea because it would probably allow for less frequent filter changes (I'm assuming the filters are pretty expensive). Where can you get one of those? What do they cost? As dusty as my engine gets I think the filter will need all the help it can get.

5) I've seen some talk about heat shields. Is a heat shield required/recommended for the 3rd Gens?

What other tips and/or information do y'all have for making the change?

Thanks.

All you really "need" is the filter. I also run the Outerwears water repellant cover and I just recently switched all the other factory intake tubing over to some tubing from Air Flow Inc. The factory rubber boot will fit over the inlet of the BHAF but it is a very, very tight fit. You have to remove the entire airbox assembly in order for the filter to fit. The filter just kind of hangs there and I took some rubber hose and sliced one side and put it anywhere that the filter was touching. I added a rubber mat below mine to help keep water off of the filter. There is an air temp sensor that will have to be mounted somewhere and I have a pic of where I put mine. It all looks cool too..

Does the air filter itself have the coupling attached to be able to hook up to the factory rubber boot, or is that something you must make and slide the filter over. Where did you get the filter?

Go to the FAQ section at the top of the page and you will find all the different part numbers from the different mfrs for the filter. They are all pretty much the same. You should be able to get one at any real auto parts store or large truck parts store.
The filter has the inlet molded onto it so all you have to do is slide your factory boot over it but, as I stated, it is a very tight fit. The good thing is that you don't have to worry about it coming off. I had an old rubber floor mat and I just pierced some holes in the corners and tie-wrapped it to the truck under the filter to help keep water off of it. It actually works pretty well..

Dodgezilla, I think you are the one I was referring to in Question 4 that had the Outerwears cover. Did you notice any improvement when you put the BHAF on?

I put my BHAF on at the same time as my Banks downpipe. I gained a little over 1 mpg and my EGTs dropped about 100 degrees. Unfortunately I'm not sure which one helped the most but I would be inclined to think the DP did.
The BHAF definitely looks better then the stock air box and now with the new piping that turbo screams!! The most incredible thing is that my wife doesn't say anything about it. I even asked her if it was too loud and she said no. I think she's a keeper.
I was already running an AFE drop-in and I had drilled the holes in the bottom of the air box so my gains may not be that drastic over what I was running...

when i installed the bhaf on mine, i first used the factory piping with a 90° steel elbow to position the filter where i wanted it. i later changed to 1x 90° steel elbow and 2x 90° rubber elbows... sounds better with the later arangement of piping.

Check out my gallery for pics of my BHAF. Everything you need to know, including price and parts list, is in this thread, page 14, second post: https://www.dieseltruckresource.com/...&pagenumber=14

The stock tube won't work with the BHAF I'm using.
