6.7L Air Filter

[JCasper]

Is it the same as the 03-07 5. 9L?

 

[CUMMINZ]

The K&N high flow filter that I added 1/2 year ago was listed for the 6. 7L... It fit my stock air box fine. I visited a business south of Atlanta several months ago and noticed they have another part number now for their high flow for the 6. 7L.

The reason I ask is Genos shows the afe replacement as the same, but the Fleetguard/Mopars as different

The thickness of the 6. 7 is a major difference

So from what I have seen there are only Mopar ones at this point, No Fleetguard crosses?



With what you are saying does the afe not fit well in one of the trucks?



I am looking to get some Air and Fuel filters for my Father-in-laws 08.

The seals are the same dimensions. As previously stated, the 6. 7l filter is taller than the 5. 9l filter, hence the difference in part numbers, and manufacturers. Currently, there is no Fleetguard filter available for the 6. 7L. The 6. 7l engine requires more airflow than the 5. 9l, so the stock 6. 7l filter has a larger surface area than the 5. 9l filter. The AFE filter is not a stock filter. It's flow characteristics are much different than stock filters. The seal area/dimensions are the same as both stock filters (5. 9L & 6. 7l), so it is considered a replacement for both. The AFE filter allows much more airflow than either stock filter, so thickness is not an issue.



Hope this helps.

Yes that helps.



Basically you are saying the seal dimensions are the same but there is more surface area of the paper element on the 6. 7L filter?



In a pinch you could put in a 5. 9L filter if needed and wouldn't have any fit issues, just reduced air flow.



Either way I will be ordering some Mopar filters from you later today.



Thanks.

Obviously, you'd want to try to avoid restricting air into the engine by using a lesser flowing filter. But, if you were in a bind, a 5. 9l filter in a 6. 7l engine would be better than no filter at all. Which brings to mind another question. If the AFE fits both boxes, why couldn't a stock 6. 7l filter be used in a 5. 9l truck. It would offer factory filtering ability, but also allow a better air flow, since it has a larger surface area? I'll have to do some investigating...

I haven't tryed fitting a 6. 7 filter in a 5. 9 box yet,but the AFE works so good I can't think of a good enough reason to try it :-laf

Good thought. Except for the 6. 7L filters costing more it could be a good way to go.

Don't get me wrong. I'm not suggesting this as a substitute for a hi-flow performance filter, such as the AFE. But, it may allow more air flow than the thinner, earlier model, stock filter - if it even fits the box.



If you change your air filter once a year, at the cost of a stock filter, you've spent enough to buy an AFE filter in three years. Change the filter more often, and the cost benefits of a reuseable filter really add up.

Definitely. The filters I ordered were for my Father-in-law, not for me.



He would rather just stick with stock stuff.



I love spending other peoples money. :-laf

I did the math! 3384 square inches of filtering surface area... ... . for the OE filter. How much "actual" filtering surface area does the K&N have? My point is that the dimensional measurements of a given filter is not indicative of it's actual filtering media surface area.

~Andy

Maybe I'm missing something here, but are you talking about changing the system and filter. That looks like a $500 job. How is that economically feasible?

 

[SBeretz]

I think he meant just using the AFE drop in filter. I think it is around 90. 00 or so from Geno's. Actually looks like a really nice filter, but I already have the AMSOIL EAA, so I will have to wait for that to wear out before I change over. Scotty
