Ordered my BHAF Thursday noon from www.fleetfilter.com. Amazingly it was on my doorstep Friday afterwork--fantastic service!

OH MY GOSH!! That is one GI-NORMUS HONKIN' FILTER! Connection was easiest thing I've ever done to the truck--besides insertinging the key into the ignition. The previous owner had used an oil-coated K&N, so I had expected to find the hose with a film of oil, but it was actually clean and dry. Checked the turbo blades and they too were clean. QUESTION: Does anyone have the constructin specs for building a "divider/spacer" between the BHAF and the turbo? I saw a link to a guy's website a few days ago, but it's no longer working. ...gotta update my signtr now...

 

go to the technical section, I think there is an actual size diagram you can print out and use as a template. Or maybe search for BHAF.

 

Search "BHAF heat shield" There should be some thing out there. They are on EBay for $50? or so. Easy To make. There is a template on here some where.
Just print out, tape together, the trace on steel.

 

I am looking into doing the same thing to my truck. Using a BHAF from fleetfilter. Do you still have the part number of the one that you used and did it fit your stock tube?

 

part 42790 works for me, tiem I got a new one, I have 40k m i l e s on mine

 

You'll need a short piece of 4" pipe to use as a coupler between the filter and stock air tube.

 

Thanks for all the info. Also i noticed all lot of people use the water repellent outerwear or prefilter. Worth it?

 

I have it on mine, keeps that paper protected a good bit better than without.

 

I don't think the paper is at risk unless you occasionally take water over the hood.

 

Got 17000 miles without prefilter and im on dusty gravel roads alot. Just wait till they go on sale at napa and then they are less than $35!!!!

Atleast they are in my neck of the woods...

 

I use the AH19004. No prefilter needed.

 

Here is that link you were asking for. This has the template for the heat shield.

Here it is right on DTR https://www.dieseltruckresource.com/...n&onlynewfaq=1

 

...ended up making my own heat shield...cost me $3.00...see link: https://www.dieseltruckresource.com/...d.php?t=202597

 

You can also drill a hole in the end of the filter and put your filter minder in it. I did.
