how does that BHAF hook up. I could not tell if you had to buy something else or if it fit right on.<br>I was also wandering what this filter is made for? does it go on a big rig or on tractors?

I hear ya Okie. We just finished up the PSD unit and need some warmer weather to do some true EGT results.<br>Lil Dog and I are going to tackle the 1st gen this week! I need his truck for sugery. ;]

Lil Dog

Ok Ok, now you've got me cornered... [shoot]<br><br>Wee One, I'll call you this week to hook up. I would like to get this done for the first gen guys... What are we gonna call this one? Wee Scotty air???LOL [disappointed]<br><br><br>J-eh

What I did was go to Lowe's and buy a PVC 'DWS to drain' 3&quot;x4&quot; reducer. The 3&quot; side fits into the BHAF's neck and the 4&quot; side fits into the inlet hose. Very tight fit, but it works great. Also gives me a surface to mount a filter minder.<br><br>I believe this filter is for big rigs, but don't know which ones. There is also a marine version for boats with wire mesh on the inside of the media, but it is about 125.00 MORE than the regular BHAF like the one in the pic.<br><br>

thanks marine you have been a great help. I hope this gives me a little more power over my k&amp;n. I hope it cuts down on turbo lag a bit.<br>thanks<br>Aaron

OK Fellas;<br><br>What is BHAF? ???<br><br>Dan

Monty

BHAF is short for &quot;Big Honkin Air Filter&quot; wich is a filter like the first gens have but somewhat bigger. Made by Fleetguard and has cross reference numbers with WIX and NAPA. ;D

Thanks Okie<br><br>After checking around for one of these BHAF's, one counter man ask me if this filter had fine enough filtration needed for my cummins. I had to stand there and look stupid, because I had not even thought of that. [NO hot air from the south, please]<br><br>So, jump in here and tell me, has someone verified that these filters are good enough?<br><br>Dan

Just got off the phone with Fleetguard, who make the stock panel filter and the BHAF. This is what they said:

BHAF= AH19037
98% efficient initial
99.9% efficient final
dust capacity- 825 gr
CFM- 687
Microns- not rated in microns

Stock= AF25541
97.5% initial
99.5% final
dust capacity- 400 gr
CFM- limited by the housing
Microns- not rated in microns

Thanks Mike<br><br>I noticed that AFE says the stock filter flows 377 CFM and theirs flows 820 CFM.<br><br>Since the Fleedguard flows 687 CFM, I wonder if the additional flow of the AFE would be noticed in power or MPG.<br><br>Your opinion please.<br><br>Dan

Marine

Dan- Fleetguard (who make to stock filter) don't have a flow rating for the stock filter. They say that it is all dependant on the housing that the filter is in.<br>If the AFE will feel or make more power than the BHAF, I don't know. But the Stock to BHAF does make more power.<br>What do they say the efficiency is? (initial and final) And do they measure it with the dust test? (1 micron to 100 micron particles)<br><br>I guess the point it comes down to is if you want to use an oil-gauze filter that costs 200.00 that you have to clean, or a paper filter that costs 35-50.00 and is throw-away.<br><br>Mike<br><br>

dan239

Thanks Mike<br><br>I am thinking about going with the BHAF. If the results are noticeable, I will post about it.<br><br>Dan

Marine

Like I said before- I wish I'd have done it sooner.<br><br>Mike

But isn't all that hot air that it draws detremental to the engine?
