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.

Get the Wix that is 4" thick.

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=FF5320&PartType=Fuel, Spin-On&Part=-&criteria=part&_locale=en
or this url and type in your filter number for specs:

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.

Yep proof proper filtration works!
