Air Filter Question

[TKarnas]

My truck has the stock air box and running stock air cleaner. I was told that the cummins is very picky on how clean the air is and most aftermarket parts do not clean the air particles as well as the Mopar stock element. I am starting to get tired of replacing the airfilter every so many miles and paying the price. I do not do any off orad with my truck. IS what I have been told a line or is this correct?



Also what type/ brand does everyone run? do I need to replace the entire air delivery system or can I just get the filter?



Thanks again

You can get an Amsoil "drop-in" air filter that is 99. 5 % Efficient@2 MICRONS, and gauranteed for 100,000 miles/4 years. Cleanable with a vacuum or compressed air. ( not to exceed 30 PSI) Will flow nearly identical to K&N. The element for your application is EAA-189.

The Fleetguard Filter for your '04 is $15. 00 at 'Geno's Garage'. Having a diesel is synonymous with 'paying the price'.

I use Fleetguard air, oil and fuel filters... . I buy it from my local Kenworth dealership...

No offense, but I don't buy that about the flow whatsoever. Study I saw, (was on TDR, can't find it at the moment), the Amsoil Nano-fiber flows less than stock, so I certainly don't see how it would flow better than a K&N, which doesn't filter worth a damn, but has better flow than stock.



I have been running the Nano-fiber filter for appx 30k miles, and in my experience it does not flow as well as the stock filter with slightly higher EGT's, longer time for the turbo to cool, and filter minder pulls down faster. I am going to switch back to stock before the summer RV/towing season.



The amsoil rep on another forum conceded that the nano-fiber filter does not flow as well as the stock paper element, but that it does filter better.

There are about 50 different types of filter systems for sale and most everyone is thinking they have the best one for their particular application. You can even build your own and put any number of different types of filters in it. I recommend you read about the ones your interested in and ask for comments about those specific ones(or do a search) and then decide what will work best for your application. If you don't find exactly what you are looking for or if they are a little pricey you can always use the stock filters which in my opinion do a very good job and they aren't real expensive.

I buy all my filters from GENO'S 4-2-1 filter maintenance Kits Then get 3 extra air filters. I change my air every tine i change oil 6000 miles. Yes I know that I not need to do it every oil change. But I like a good air flow to my eng.

Stay Away From Less than 7 Micron

Dont even think about a K&N. Been there done that there is a reason they flow so good, they dont filter anything.



K&N, Amsoil, or any other filter for that matter that is less than 7 micron should be for street use only. And even then I wouldnt run one. I use the AFE drop in with 7 micron filtration.

It seems to me that if you're having problems with stock filters plugging too quickly, a BHAF would be a good option with its excellent filtration and larger surface area.

I run a PSM system with an AFE Progaurd 7 filter. I have been very happy with it.

You should be running the filter until the filterminder indicates it needs changed, but most filtgerminders fail early on in life.



Just keep in mind, the more plugged a filter becomes, the better it actually filters with a sacrifice in airflow. They don't start releasing or passing dirt into the air stream as they get dirty.



I run fleetguard and baldwin air filters and UOAs show they are filtering well. I change them when I feel like it and typically around 30k... mostly road miles.



I found that, in my situation, reuseable and cleanable filters don't clean up well enough when they are cleaned. I get an oily "dirt" that is not easily removed during typical cleaning.

steved is correct, do not overservice the filter and that proguard-7 is junk every one i have seen you can shine a light in them and see voids in the layers of media and the afe oiled has light shining around the stitches like the k&n

The only other thing I would ask is that you state the change interval you're using... and why you think the filter is plugged.

 

[TKarnas]

First thank you for everyone taking the time to send their oppinions.



I change the filter about 10K miles. Not so much dirty but what I was told to do my the dealer I bought the truck from.



I thought getting a reusable filter would be easier, but from what I see I might just stick with the replacements from Genos.

 

[steved]

10k is probably way to early if you're not offroad or in dusty conditions.

As I noted, I run on average around 30k per filter and the filter-minder never moves. The filter is still fairly clean when I pull it (still see daylight through the pleats), although the pre-filter is typically pretty dirty. Most of my miles are on-highway, with some off highway driving to reach sampling locations.

Also, I base mine on fuel mileage more than anything... a consistent drop in mileage (less than 1mpg) is typically my indication that the airfilter is restricted even though the filter is still fairly clean-looking... a fresh filter typically brings mileages back up. But this assumes you document your mileages regularly.

Tip: If you want to run Fleetguard, go to your local big rig dealer, I go to my local Kenworth dealer, and piggyback on one of their commercial accounts. Just ask the parts guy if there is an account you can buy under, then just pay cash or CC. I am buying the Fleetguard AF26106 air filter for $7. 95, with similar 40% to 50% discounts on other Fleetguard filters. The parts guys are happy to do it because it helps their commissions on their commercial accounts.

It is a high quality stout filter. I was impressed with the physical quality of it. It replaced a Wix that felt flimsy in comparison.

BrianJ is right, I saw that same study and decided to stick with Fleetguard.
