Air Filters For Your Trucks

Nope just wanting the best product available. Example I used to run the FleetGuard Stratopore oil filters but since the AMZ/OIL-Donaldson are a better filter i have switched.

Don't think you will get a better stock air filter than the FleetGuard/MOPAR.

But what if the Fleetgaurd/Mopar is the exact same as the Wix coming out of the same factory? I bet if you did a little research, you will likely find that they are procured from the same company. Contrary to popular belief, filter manufacturers do not make every filter they sell. Many times they will buy from a competitor and relabel it if it is cheaper to do so or if the competitor still has a patent on the filter. Since Mopar does not make their own filters and Fleetguard doesn't make this filter, they are both likely getting this filter from the same company that Wix is also getting it from.

It is like vehicle batteries. There are only three major battery manufacturers in the US. Clarios(used to be Johnson Controls), East Penn, and Exide. These three make all those battery brands people fight over claiming one is better than the other. The last time I visited Clarios(who makes our branded battery for my company), I saw interstate batteries come of the same line as Motorcraft batteries. The only difference is between each brands good/better/best batteries which may have a different virgin lead content. is bonded, and/or has some other accessory like a handle. However, all "good" batteries from every brand comes off the same base battery line, just like all of the "better" comes of the second tier assembly lines as well as the "best' coming off the tier 1 assembly line.

In regards to Fleetgaurd's Stratopore, they actually sold this synthetic media to many other competitors when it first came out because these competitors did have the means to make it. This synthetic media was made specifically to Cummins' spec so even if Donaldson or Amzoil has a better filter media(which I don't think they do based on my data), it will not do anything to extend the life of your engine so it is basically pointless especially if it costs more. If you can show me where the Donaldson/Amzoil filter will extend the life of my engine X amount of miles more than the Fleetgaurd, then I might be intrigued.
