View Full Version : BHAF
11-18-2002, 07:57 PM
All right, my truck's a year old and I'm looking into getting a BHAF or something similar to it. I do NOT want a K&N. I love their products, but believe I've read too much about the oil getting all into spots it shouldn't be. Therefore, no K&N or products like them.<br><br>Where can I get a BHAF or a similar product? What do others have? Benefits? Sound? HP? <br><br>Thanks in advance.<br><br>Toby

Here (http://www.dieseltruckresource.com/faq/faq.php?display=faq&nr=54&catnr=10&prog=1&lang=en& onlynewfaq=1) is a link to our FAQ. We have added the cross reference part numbers for the BHAF. You can get the BHAF from just about anywhere that stock the cross reference filter brands.
I am running a Fleetguard BHAF, look in me photos in the members section for pic of my BHAF, cost me 40.00 for this filter.

<br>So, I go buy one of these filters and it plops right in?<br><br><br>yep, take oyur stock air box out and connect your BHAF to the big black hose ;D
Sometimes there might be a problem cranking the ring clamp down on the hard rubber lip of the BHAF -- it distorts. If you find that happening, a five-inch section of four-inch thin-walled PVC pipe inserted between the hose the the BHAF rubber lip provides a hard surface to mount both ends to. <br><br>GP

I use the NAPA bhaf, no problems with distortion yet. How many out there are running the filter without a mount? I was going to but decided to build one out of our scrap pile.
I don't have a mount for mine, ::)

I'm not using a mount, either, but I did cover the exposed studs that the<br>stock air box is attached to with short pieces of surgical tubing so they<br>wouldn't rub holes in the filter. I have the plans for the shield, but haven't<br>gotten around to that, yet.
Actually I'm not running a mount or a pipe, either -- although I do have the filter lying on a pad and secured to a heat shield. But I've seen some difference in rigidity of the intake lip of different BHAF's -- the first one I bought was softer than the one I have now. Don't know why -- I thought they were all made by the same manufacturer and sold under different brands. <br><br>GP

More praise for the BHAF.<br><br>I dynoed 447hp with mine, friend of mine Aaron Otte dynoed 470hp with his.<br><br>After I get to about 500hp then I'll start thinking of switching to a different air filter.<br>--Justin

No mount on mine. I put a piece of 1" thock soft rubber over the bolts sticking out of the fender. The filter just lays on it.

Got mine just laying there. I would like to see what ideas you guys have for a heat shield / mount for them. Would it make that much of a difference ?
Funny story ..
I had a buddy ride with me near the end of the air strip here on base. As the turbo began to spool up, he started looking all around trying to see the fighter jet that he thought he was hearing.
Nope, no fighter jet ... just a BHAF !!! [laugh] [laugh]

Pistolwhipt- I have the heatshield template if you want it. Just e-mail me at home. (Mike_glenda@yahoo.com)
I also have a 4-3 pvc reducer between my bhaf and hose. Looking for something different.
I'm currently running an informal "test" of a K&N in my drilled airbox - carefully monitoring intake venturi of the turbo for signs of dirt buildup - after about 5000 miles or so on the stock filter, I carefully swabbed that intake with a clean tissue, which I then carefully saved in a sealed wrap, then installed the K&N - in another few thousand miles, I'll do it again on a clean area of the same tissue, and compare - pic below of what a stock filter lets past...<br><br>If I'm not happy with what I see, I'll convert to the BHAF - sure would like one of the neat stainless steel mount/shield setups one fella was making and selling for a while...

someone asked for a pic of the hsing for my mhaf. made from allmnm pipe w/ hole cut for fender air. also hole cut in cowl area to utilize the cool clean air there. the allmnm absorbs too much heat so some other material be bettr. it will be replaced w/ a stainless version. im still wishin scott will manufacture a scotty II for a mhaf<br><br><br><br><br>this aint the purtiest but it is temporary till a stainless version is made

I did the same thing but in reverse but I didn't save the wipe. After 3K miles, I swabbed the inside of the intake at the turbo blades and the swab was black. It was oil and I immediately removed the K&N and installed a BHAF. 30K miles later, still no dirt on the intake at the turbo.
Here's a pic of my BHAF, with the heat shield made from Marine's template. The filter is a NAPA #2790.<br><br>It seems to work great, you can hear the turbo spool up really well! The EGT's are lower than with the stock box, also.

Could someone please post the measurements for the heat shield? I got the file from Marine but have since moved back to school and the computer here won't open it for some reason. Thanks for any help!
