Cummins 5.9 Filters

[Gulfcoast]

2006 Dodge 2500 Mega Cab
5.9 Cummins
150K miles

Just picked up this fine, clean truck and it has to last me a long time.

Would someone please give me the correct Fleetguard air, fuel and oil filter part numbers please?

THANKS for your help.

Oil and filter changed, fuel filter changed... now, what air filter do you recommend for the 2006 5.9?

No K & N filter or similar.

Thanks

FleetGuard or Mopar what ever is less $ as they are the same.

Thanks, I'll tell the guy that bought my truck.

Diesel fuel Filtration requirements for a common rail high pressure system are much difference than the requirements for a low pressure mechanical pump system. Both systems are severely damaged by very small amounts of free water in the fuel.

High pressure systems are damaged easily by ~5-7 micron particulate. Especially if emulsified water is also present.

If you want an eye opening read - go to the Bosch website and research cp3/cp4 series pump systems in regards to fuel specifications.

Caterpillar a few years ago did some extensive studies on diesel fuel filtration needs of a high pressure common rail system. These studies are available on the internet with some searching....

On fuel filtration - you cannot get hung up on the "micron rating". It really is a meaningless number unless you have a few more facts. Like the Beta ratio of the filter. Or the nominal and absolute micron ratings.

Most don't understand that the high pressure fuel system really has two contaminate sources that take differing filter media to minimize the risk of injection system failure.

Particulate

Water

The filter in the previous post, if a FF5320, is a 5 micron @ 98.7% efficiency as tested to SAE J 1985 standard. It also does not protect against water.

The FF5320 is a 2 micron filter, as advertised everywhere, and is installed after a 7 micron filter/water separator.
You can reference any stats you like, but thats the listed specs.

Just because it is stated on websites everywhere -it must be true....

Check this page for Cummin's published specifications:
https://catalog.cumminsfiltration.com/catalog/partsearch.do?&reqCmd=PartInformation&partNumber=FF532...
or this url and type in your filter number for specs:
https://catalog.cumminsfiltration.com/catalog/CatalogSearch.do?&criteria=part

IMO use of FF5814 will get you a little better water protection than the FF5320. Also, will do much better in very cold climates due to the synthetic media (nanonet)

I use a Donaldson P553203(short) or P553207(long) filter as it has a better rating both particulate and water trapping as a first filter. It has the same 1-14 thread mount as the filter you are using.

Mapguy.... So, what filter do you recommend for a 2006 5.9?

Yep proof proper filtration works!

Amazon is where I get mine now. There is a Filter Service warehouse that strictly sells Baldwin that I pass daily during my commute but their prices are so high. I can get 3 of the Baldwin BT7349 oil filters I use on Amazon for just about the price of two that they sell. Same with the Fuel Filters.

Heck I just bought Rotella from Amazon 😉

"Can't say why, but many on the forum discourage using one of the transmission flushing machines."

TRUE, but I did not recommend "Flushing" I recommended "EXCHANGE" BIG difference.

VERY easy to do and you get virtually all the old fluid out.

I want the best filter for sure. Thanks

What about servicing the transmission, since I just bought it?

Get someone to do a complete fluid "EXCHANGE" and adjust the inner and outer bands. Or do it your self as it's not hard to do at all.

You have to drop the transmission pan to access one of the adjustments for the bands, not the most pleasant of jobs. You will also need a quality low range torque wrench. Best to do this job when changing the transmission filter which is also available from Amazon.

I bought my Ram with 62k miles, it shifted kind of clunky. I dropped the pan, changed the filter and adjusted the bands. I also replaced the pan with one with a drain plug. I filled with Castrol ATF+4 (Amazon) and drove for thirty minutes, drained off 7 quarts and refilled. 100% improved shifting performance. I now splash and fill 7 quarts of ATF every other oil change. really simple.

Can't say why, but many on the forum discourage using one of the transmission flushing machines.

My question would be that if Cummins had wanted a 5 or smaller micron filter, would they have required one by Dodge?

Cummins sold the engines to Chrysler with no warranty. Cummins had therefore no interest in what people were running.

The engine is mounted with a Cummins/FleetGuard filter right from Cummins.

Mounted to an engine sold with no warranty.

Was not disputing that! Cummins found out that a better filtration system was needed with the injectors being damaged due to needing smaller micron filtration.

This reminds me, mine could use a new filter. Ordered one on Amazon, the Baldwin.
