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

That'll save me alot of money since I replace the stock filter at least three times a year @ $23.00 each.

If you are using stock OEM filters you can get the Baldwin PA4162 for $11.38 each if you buy them by the case of 6. http://www.bfwebexpress.com/catalog.asp

Eric at Vulcan has the best price on BHAF's that I have found at $39.99: http://www.vulcanperformance.com/Big-Honkin-Air-Filter-BHAF-p/bhaf.htm

when i pop my hood and everyone sees that BHAF.....everyones is like"whoa" or "did you pillage that off a CAT?". it lasts a long life and i am happy with mine...DROP INS SUCK!

nanofibers are available as dropin or as a large cone. supposedly allowing more airflow compared to a bhaf. still trying to decide ofcourse because they are just over twice the cost not counting outerwears cost on bhaf. as far as life span I swore my filter-minder was broken till i ripped it off the stock airbox and tested it. the sponge covered paper filter I have in there is still relatively clean.

Thanks that's a great deal. I wrote that # down too.

The OEM paper filters work great as long as they meet your need. In my case, I went to the BHAF out of necessity. The OEM filter and box just could not handle enough air with the Mach 1.6 injectors and Edge EZ combo. Just not enough surface area or box opening to flow enough air. They work great on the wife's truck.

except for my exhaust, my truck doesnt really have any performance mods. looking at the bhaf or nanofiber filter merely from a fuel economy point of view.

Unless you just want a BHAF under the hood or plan to add mods later on, the BHAF on a stock configuration truck is wasted money. The ECM is going to limit fuel at approx. 20 psi boost which is well within the capacity of the OEM air box and filter. The BHAF does look and sound pretty cool especially if the silencer ring is removed. Some like the noise, some don't. I left my ring in.

Intake and Exhaust Restriction

An engine that is starved for air (intake restriction) or unable to expel exhaust (exhaust restriction) will lack power and waste fuel. The extra fuel burns inefficiently at best because it takes air to completely oxidize the fuel and extract all of the power that it contains.

which is why i was looking into it

Its your money. Spend it how ya like. That is what makes this country a great place to live. You will find that the greatest increase in efficiency and fuel economy with these trucks is hidden in the right foot.

oh I totally agree with that, just trying to get the mechanical aspects as well

I think I will keep my truck fairly stock. I own an Outlaw late model race car that'll give me a thrill on the race track when I need it. The problem is that if I hotrod my truck I can't keep my foot out of it, lol.

i love mine...got me a black outerwears for it too....

That's exactly what I'm runnin' even the same color.

So i've been reading this thread and saw the post about it kind of being wasted money on a stock truck...my trucks pretty well stock except for the lift pump and I have the XZT, would this upgrade still be a waste in my case? Also, how does the BHAF fasten in, or is it big enough it basically just lays in there and stays in place on it's own?

Well the fact is you won't have to change air filter for about 6-7 years... Never got to wash it, never got to oil it, etc... Just stick it in the rubber neck of the elbow and tighten up... Like myself I created a heat shield for mine. Then tied it down with a bungee cord. Then beefed up the neck with a piece of 4" exhaust tubing. Then top that all off by stuff the stock filter minder in the head of it... My first filter cost me $58 buck at a local part store. Then I bought a BHAF replacement from Eric at Vulcan Performance. As of right now that new filter is still sitting behind my desk in the box 1 year later waiting for the first filter to start pulling the disc down in the filter minder... But to give you an idea.. I've still got factory brake pads yet after 162K miles... I figure my first brake job will be at 200K miles... (Thanks to Mr. Exhaust Brake) There is a lot of things that you can add to your truck to extend the life of everything!

BHAF all the way - I like the spool up I get on the turboAnd its only like $100 with outerwears (or less) as opposed to $200-$300 for similar filtersI have mine bungied in as well (stitting on thick cardboard at the moment) I also cut out a little of the heat shield fabric on the corner of the hood to ensure it doesn't block the BHAF - pretty sure it works and helps more air get to filter Just a small section directly over filter where not too much heat exists ;)

well this is my first post on here..i like my bhaf

What kind of cab noise do you get from it? A muffled sound ,or maybe i'll compare it to an old 350 engine with a cookpot air breather flipped upside down?

Whistle.. That's all there really is to say about it, you can finally hear more whistle.
