For all of you that are looking to help you Cummins Turbo Diesel breathe better well there is several different kits, filters, etc. on the market. I'm not going to bend your arm to follow my lead but I will explain why I made this choice.First off there are filters like K & N on the market that are washable and re-useable. Well I'm going to suggest you forget using these filters. When you wash a filter your going to put wear on the media and eventually open holes up in the media to allow passage of dirt. Another problem is most people over oil the filters and the turbo sucks oil in on the compressor wheel. If there is a dirt leak you will see a dirt compressor wheel and it will cause turbo damage.So when you look at a BHAF or similar filter you will see a completely sealed unit. There is no way for dirt to get pass the filter into the engine. Also the BHAF is roughly 3x bigger than the stock panel filter so this allows more air to enter the engine unrestricted. Another bonus is the media is a dry paper element so the dirt will not stick to the media and cause it to plug premature.The down side to a BHAF is the price. They are roughly $50-60 bucks. So if your smart you buy a filter and get the outerwears pre-filter for it. It will protect the filter from heavy dust and water. It will make the filter last for a very long time.I've gotten about 60K miles on my BHAF now and it is now just getting really dirty.Here is also the listing of different part numbers for a BHAF below...Part Numbers of BHAF filters

Nice Rig - I like the chrome on the bed and the grill/scoop

Hey guys I found some BHAF filters for 40 bucks here at a filter place let me know if any body needs some.

Good info on the traditional paper BHAF. I am running an AMSOIL Nanofiber 4510. It is also a dry filter and costs about the same as a BHAF. I can also clean it with compressed air. I still have my old BHAF that I used to run, and it was a great filter. I'd like to see comparative CFM testing side by side with the Nanofiber and the traditional BHAF. Based on many customer reports, the Nanos have yielded more turbo whistle, lower EGTs, and quicker "seat of the pants" spool up. Of course, the overall point to all this that I think most diesel guys will agree to is that the key to good air filtration on diesels is to run a dry filter. Oiled filters start to cause problems in the real world under the CFM demand stress of these engines. -Chuck

I've been running the Amsoil Nanofiber EaAU4095 with the EaPF12 pre filter on mine for approx 11months. Have been very happy with it. This filter has the hole for the filterminder in it as well.

Now test your filter minder now and then and you'll see the how light of a suction is needed to pull the filter minder down... I'm still waiting for my filter just quit and suck the filter minder down but it just won't die.

I am with you Chuck on the nanofiber technology I have one with the prefilter it breathes very well IMO. I had the oiled type and it fell apart went with the EAAU4091. Bill

I ordered my BHAF and outerwear from Vulcan last week and its supposed to show up tomorrow. My question is how exactly is the BHAF mounted? Have you guys mounted the filter down with anything or do you just have it sitting there under the hood? Just curious and I have been looking around at a few different sites and couldn't really find an answer as to exactly how the BHAF is mounted. Can't wait to ditch my K&N drop in that was in the truck when I bought it for my BHAF tomorrow!

I mounted a turbo heat shield in place of the OEM air filter box and the BHAF lays on the heat shield. I use a bungee cord to hold the BHAF in place. Use a bungee cord long enough to just hold the BHAF in place and not too much tension as their is not much else but the A/C lines and the OEM fender air inlet to hook the bungee too. I have had mine mounted like this for about 2 years. Works great.

Ok - afraid to say - but I have mine sitting on a piece of heavy cardboard over the bolts that held the orginal OEM filter in place, with a snug bungy cord over the front of it where its clamped to the airintake tube going to turbo, same as LiveOak.

Heatshield is best way as at least it offers some protection but also the bit I like best you can mount it properly on those bolts so its a firm connection and you don't damage the filter. I am going to do mine - I just need to get my brother to weld me one off the templates (you can download from this website).

I cut back the fire-blanket on the hood just enough in the corner so it couldn't fall and restrict the air flow of the filter. Seemed to work better for me - but mine is a little raggedy - I was concerned it had enough flex in it that it would sit on top of the filter - this way I know it isn't

Here's the heatshield download templates and some pics

I got to build one for my 2001 out of Mikes templates check it out let me know what you think.

My heat shield is identical to the heat shield you show. It is made of diamond plate aluminum and works great. Looks great too!

Get a piece of old rubber hose split it down theside and put it over the freon line to protect it from rubbing from the BHAF...

OK will do. Question how do you adapt the filter minder ? and how do you take it off the box? Thanks for the tip !

You just twist and pull. Like he does in the vid here http://mopar.mopar1973man.com/personal/2002/bhaf/bhaf.htm You have to drill a hole on the BHAF for it to fit in to.

Thanks for the replies. I wanted to get mine in once I got it yesterday and and WHAT a difference! Can definitely tell a difference in turbo spool up and just from today I think I'll see a mileage increase as well. A MAJOR improvement over the drop in K&N in the stock airbox. I wanted to get it in and didn't have the time yet to make up a heat shield. As backwoods as it sounds I covered the air box studs with some cardboard and duct tape. I set the filter in and came up with this little tab to zip tie the filter in place mainly just to keep it away from the hot exhuast and cause a fire.

Love that front bumper...Where'd you get it/Who Makes it?
