Cummins 5.9L Air Filter Part Number Needed

Hello,
I have a 1994 Fleetwood Bounder with a 230hp 5.9L mechanical Cummins diesel and was wondering if anyone knows the part number and where I can acquire an air filter for it. The canister is quite large but I didn't see any part numbers on it. Any help would be greatly appreciated! Thank you in advance.

I would contact Cummins Care for your motor home. Here is a link to their site.
http://cumminsengines.com/every/customer/cummins_care.page?

I would provide them with the engine year, serial number of engine and displacement of engine. They should be able to tell you what air and any other filters part numbers you need.

It was all good info right up to the part where you think Cummins knows which air filter the MH was built with. Choice of air filter is the responsibility of the chassis OEM. Contact them. Most likely the air filter will be a Farr EcoLite series, a disposable housing air filter.

Cummins Air Filter part number

I have a '98 Discovery, 5.9 ISB. My air filter is a large cannester accessed from the rear drivers side bay. You might check..Farr # 114810002 or
ECO # LAF 2521 or GAFP #103723.

Good Luck, Chuck

Get a Heavy Duty K & N filter. And never have to buy another filter.
K & N can be washed with a power washer if it ever gets that dirty.
Price is about same as 2 OEM filters. After that it is FREE.

Spike45,

Gary, have you seen any data on the K&N heavy duty line?

I would not put a K&N filter on a furd truck even if you paid me to. Some time ago Cummins did an air filtration test with several aftermarket filter manufactures. When they were down with the testing it was determined that K&N Filters were detrimental to the engine causing premature were on the Turbine and cylinder walls from high levels of SILCON. Cummins states that they would void the engine warranty if they were found CAI intakes from K&N on the engine.

Yes, I have read their website data claiming an overall efficiency of 96% dust removal. That is about the same as the oiled foam 'air cleaner' on a cheap Brigss lawn mower engine.

In the world of real air cleaners, 96% efficiency is a whopping failed part. Donaldson, Baldwin, Fleetguard all use 99.4xx% as the bottom threshold of an acceptable air cleaner performance.

Put another way, for every 100 ounces of dust that the K&N will see, it will allow 4 ounces through.

Real air filters receiving the same 100 ounces will allow 0.6 ounces through. In reality, these real air filters typically perform at the 99.9xx% overall efficiency. Frequently, we saw returned Fleetguard air filters that reported in at 99.980%. It is not uncommon at all. These would have passed 0.02 ounces.

An ISL, ISC can be dusted with about 5 ounces dust. ISB about the same or slightly less.

K&N and another brand (AFE?) have as a product feature the re-usability aspect for sure. But as you can read above it comes at a great cost. A tip to anybody looking to buy a pre-owned MH, if it has had this type of air cleaner....keep looking or plan to get the price down enough to pay for the at minimum in-frame overhaul needed to fix the dusting issues.

Speaking of dusting, the bad news besides the obvious need to rebuild or replace the engine is that it does not show up immediately. There is usually enough time to trade it off before anybody notices the increased oil consumption and high blowby. In fact, you could consider getting the engine tested at a Cummins distributor to see what the blowby is on the MH you are considering. Not sure if a dealer or owner will like that but you can guess how important that is to you.

In the test documents you have seen. How much does the K & N shorten the mileage life on a Cummins engine.

Need to be rebuilt if a K & N filter is used at 100K, 200K, 300K maybe 400? Will never being driven on dirt or gravel roads extend the miles?

If you read the web site, why not include the up to 99%. That would make their overall % higher then you posted.

From K & N web site
Our actual air filters when tested generally demonstrate a cumulative filtration efficiency of between 96% and 99%. All this testing we do allows us to guarantee our air filters provide all the protection your vehicle will ever need.

K&N Filters performs air filter tests for efficiency and capacity in compliance with the ISO-5011 Standard for Performance Testing of Inlet Air cleaning equipment for internal combustion engines and compressors. Previous to the adoption of the ISO-5011, testing was performed in compliance with the SAE J-726 - Air Cleaner Test Code. The ISO standard states that the basic performance characteristics of greatest interest are air flow restriction, dust collection efficiency, and dust capacity. K&N adheres to the ISO standard in the measurement of these test parameters.


That would lead a reasonable person to ask what then is a safe level of filtration. This question is literally unanswered. Minimum air filter specifications are generally not called out in vehicle owners' manuals, nor will you find much published information on air filtration requirements from vehicle manufacturers. We have never seen a scientific study concluding what levels of filtration efficiency correspond to various levels of engine wear. Some large air filter companies do not even publish information on the efficiencies of the air filters they manufacture. It is K&N's opinion that both the Fine and Coarse Test Dust mixtures used in air filter testing contain such a high concentration of small particles that even filtration efficiency numbers as low as 90% may provide adequate engine protection. Remember that almost 11% of COARSE test dust is smaller than 5.5 microns (the size of a red blood cell). For a detailed explanation of our testing protocol.

Spike is right-on. K&N's are for race tracks,not highways. Any air filter that guarantees you more performance is going to offer you less filtration.
