BHAF
 

this may a dumb question, but im looking at getting rid of my k & n intake system and converting to bhaf with custom heat shield by Tad Murata. where do you guys that have the BHAF get your filters? you order them online? thanks in advance!

Here is a cross referenced list:

BHAF numbers
NAPA # 2790
Fleet Guard # AH19037
John Deere # PMAH19037
Wix # 42790
AFE # 20-40044
Hastings AF 1012
Carquest # 87790
Caterpillar 3i 0005
Fram CA 6818

just came across it my self!!!:c:

I usually get the 2970 from Napa

you guys just run the stock tube from your factory intake? or you fab something up?

I'm with the stock for now, makes the turbo sound sweet as hell though!

just replace the k and n with a s & b filter they flow better than a bhaf.

got the Napa BHAF, just looking to change things up a bit. im kind of curious though as to how the BHAF's look...anyone got pics of theres??? just wandering because i may fab something up for mine.. pics greatly appreciated. :yeah:

It ain't mine, just googled it and this is the best one that pertains to our pickups.

Thanks bud... appreciate it. it looks like the filter just floats under the hood.. is that true? Im getting a heatshield built by tad murata, hopefully that will look good. :yeah:

I was surfing around looking at BHAF pics and stumbled across a write-up and a printable heat-shield template.

http://dieseldatabase.com/bhaf-big-honking-air-filter/ This is the link to a BHAF write up and near the bottom is a link to the template that you can download and print. I saved it to my desktop but for some reason it wont let me upload the word document.

Thanks Ugly Truck... i may try and fab my own heat shield... it doesnt look too hard. As far as the pre filter, is anyone really using that? im not sure its worth it.

IMO >I think they are totally worth it. as much as the BAHF costs, if I can block the large particles first before they get into and clog the pleated filter and then rely on the pleated filter to catch the small stuff I personally think it will more than double the life of the BAHF. We have run them on air filters and oil breather filters on the dirt track cars forever specifically for that reason.

I have the prefilter on my truck. It helps resist water, and catches a lot of dirt.

Why are you guys still using the BHAF when you can get a WASHABLE dry filter that will last you forever for a couple of bucks more than the BHAF??? It makes no sense to me at all.

Because I don't want to drop another 200+ bucks on a new cold air intake at the moment when I have other vehicles to take care of as well.

You dont have to - you can just buy the FILTER...same as buying a BHAF except you can WASH it :se:

well i got a BHAF and also ordered the prefilter...will have it waiting for me when i get home from south korea(in march of 2013) any other homemade ideas for the 24v cummins is what im looking for. Thanks guys!! :tu: :moon:

You dont have to. Its just like Dr. Evil said. There are two filters from Amsoil that are becoming popular for this, one has a 4" inlet just the BHAF, just swap it on there just like the BHAF. The other is a larger filter with a 4.5" inlet, that requires a little PVC adapting.

The 4090 4" inlet
Amsoil EaAU 4090 Nanofiber Air Filter - Icebox Cold Air Intake Systems

The 4510 4.5" inlet
Amsoil EaAU 4510 Nanofiber Air Filter - Icebox Cold Air Intake Systems

They are both dry filters, do not require oiling. I wont bother you with details, just do some searches on this forum or google about them. Less filter area than a BHAF, but flow better, and still filter well.

the pre filter really cuts the flow down on the air filter. I would not run it if you want it to breath...
