Somebody Explain Air Filters To Me
 

I've always wondered about all the different makes and models of air filters out there for all the diesel truck, both pick up style trucks and big rigs. I understand that each truck has a minimum amount of air flow needed to feed it but past that what's the difference. Why couldn't I take a filter off a Duramax and install it on my Cummins or for that matter any filter on the market that meets my air requirement and use it.

I dont see why you couldnt, as long as the filter wont suck in from the boost im guessing any that will flow the proper CFM's you should be fine...

Ever seen the filter out of the newer Chevy's or Fords with the diesel?? Amazing they even run at all. That and they run about $100 and your not suppose to change them till about 10k miles. The heck with that.

get a K&N.... clean it every other oil change..... best filter you will need

Have already had the K&N Canon filter for ten years now. This is just a question about the sciences of filters and not which ones are better. I leave those arguments for others.

K&N has not been known to be a very good filter.

:ouch:I must not be explainin this right. Don't want to talk brands, that issue has been beat to death on ever forum for decades. I wanna talk mixing and matchin filters that are listed for different applications and what info needs to be known if I want to run one listed for somethin different on my truck. If I wanna put a Massey Fergusson Tractor Filter on my Cummins truck tell me what I should be lookin for to make sure it would work.

cfm's and how they are cleaned is what i look at. i get tired of $40-$50 every filter with paper media so i wend to a reusable. if your turbo can only take in so many cfm's than a better breathing filter could be a waste. just my look at it. i believe a hx-35 is 570 cfm BHAF can move 800 cfm to the turbo.

That's the stuff I'm lookin for thanks. Now keep the info comin.

A diesel engine doesn't meter air, so as long as the filter meets the CFM requirements of the engine cubic inches and estimated compressor capability, the filter will work on the engine.

There used to be a formula--something like the filter at 50% capacity should be able to flow 10% over the maximum requirement of the engine package, or something like that...I remember reading it once in a racing publication but cannot recall it completely.

There really isn't such thing as a "too big" air filter for a compression ignition engine like there is for an engine that relies on metered air and vacuum to work properly.
