5.9 & 6.7 air box & air filter
 

Does anyone know if the stock 6.7 air filter flows more than the stock 5.9 air filter?

Can the 6.7 filter fit in the 5.9 air box? if not can the 6.7 box fit in the 5.9?

Thanks

A little searching here will answer your questions I'm sure, but I think the 6.7 filter does fit the 5.9 air box and I also believe it flows better as well. I do know it has been talked about here in the past.

It does fit and should be used for better filtering. The 6.7 filter is what you should get if you go in and ask the dealer for a replacement filter for like an 06.

How's it better? If you use the new style 5.9 filter it is the exact same filter other than the dimensions. The 6.7 will fit a 5.9 air box, but the pleats hit the bottom of the air box.

6.7 Dimensions
10.93" Long
9.91" Wide
4 3/8" Deep

5.9 Dimensions
10.75" Long
10.00" Wide
4" Deep

the 6.7 filter will not fit the 5.9 box. we were changing our 5.9 boxes out to the 6.7 boxes when wix came out with a filter that fits the 5.9 box it is 49946. this filter along with the wix 46930 for the 6.7 has half the drop as a stock 5.9 filter and filters better

Huh? What drop? Pressure Drop? Old style 5.9 filter max pressure drop = 0.36 psi. New style 5.9 filter max pressure drop = 0.51.

Yes, the new filter from wix is the 49946. Napa # is FIL9946 and the Mopar # is 53034249aa.

Some info...

53034249AA (New Dodge air filter) identical to WIX P/N 49946 and Napa P/N FIL9946. Printed on the filter it states that it has a dust capacity of 540g, max air flow rate = 675 cfm, max pressure drop = 0.36 psi. It has 42 "pleats" and they are 3.75" tall. Efficiency is 99.6%. Cost is approx $26, but may be as high as $33.

53032700AA (Previous Dodge air filter) identical to Fleetguard AF26106: Printed on the filter it states that it has a dust capacity of 450g, max air flow rate = 675 cfm, max pressure drop = 0.51 psi. It has 88 "pleats" and they are 1.75" tall with a 7/16" thick foam pad glued onto the bottom. Efficiency is 99.5%. Cost is approx $21.

Amsoil EEA189: (Nanofiber stock filter): Has 46 "pleats" that are 1.75" tall. Filter media feels like paper. According to PSM website, has dust capacity of 39 grams. Efficiency is 98.3%. Cost is approx $36-50.

aFe 30-10102: (Pro-Guard 5): Has 22 "pleats" that are 1.25" tall. This is an oiled filter. Don't know the dust holding capacity, but this is the old oiled filter from aFe with lower efficiency. Efficiency less than 99%. Cost is approx $70.

Thanks for the info.

If I understand you guys corrctly both the new OEM/Cummins filter and the old OEM/Cummins filter have a CFM rating of 675 so there would be no performance gain by switching to the new filter.

Thanks

i am pretty sure I have one if you need one. if I do you can have it for shipping costs.
