John, The filter I just installed from Freightliner is a RACOR-- FARR ECO 114880-003, my understanding is that Farr makes these filters and they are re-branded by Wix, Baldwin, Fleetguard, Racor etc.

Diesel engines suck a lot of air and are very susceptible to ingesting dust with disastrous results.
K&N has apparently come out with a new filter for diesel use. I don't know how it compares in efficiency to the paper filters.
Here is a test and evaluation of several filters, K&N did not fare well.

A lot of people will tell you not to do it.

I agree with them.

Same reason. Dust in the intake after just a few months of usage.

K&N filters are JUNK! They flow more air and much more dirt than a good filter. On an engine with a MAF sensor, the oil from the filter will cause problems.

After working 30 years as certified auto tech, I have replaced more mas air flow sensors due to dirt contamination with k&n filters tan just for wearing out. Please, please do not use these filters. I had asked a k&n rep about dirt intrusion while using his product and he could not give me an answer!!

Thanks everyone, looks to me K&N is out.
I will buy a new filter each time, I am able to change it in less than an hour now.
It would probably take an hour to clean a K&N and you still have to take it out and take it apart.

There is an extensive cross-reference for a 114880003 I wonder where is the best place to buy.

All the best, will be in Centralia next week to install a MP-8, soon to be 400+ HP

Some have said "more air flow equals more dirt", not totally true.
Increasing the filter size and if the intake to the filter will support the increase
in air flow will increase air flow.
A some what new filter out is the Nano-fiber filter but currently none for our motors.

I believe the folks who built the engine know what's best for it. I use the stock filters

Land Barge · 09-04-2013, 04:46 PM

If more dirty becomes more efficient, does that mean if I put a plastic bag over my air cleaner it becomes 100% efficient?

Actually yes with regard to dirt ingestion, not so good for airflow.

I never like that comparison. It's only more "efficient" in the size of particles it will allow by by having smaller and smaller places to pass by the already there dirt and by extension less area for air as well making it less flow efficient.

Good quantity air filter and changing regularly is best money spent.

In most cases the engine builder has little or no control over what filter
or it's install by our MH builders who use the smallest they can to fit in the
space allowed and the cheapest.

But the engine manufacturers do specify an air flow requirement for the unit and the chassis manufacturer goes by that.
