Grizz I have Two for my 04. 5 I like them I clean the one I take out and reoil and put it in a freezer bag and install the other. Then when I change oil at 7K I install the freezer bag one and clean and reoil the other. By putting it in the bag it lets the oil saturate the filter more evenly than just cleaning and installing BTJMO

There may be places that the Airaid and the K&N filters will work just fine but if you come to West Tex, you had better have something better than that to filter your air. Try putting you a little grease on the inside of your air tube after your air filter. Where I am, in a very short time there will be dirt on the grease. If you do a regular filter that way there will be a very small amount dust that will collect.

I have a couple of filters that is for sell cheap.

Yep, I agree completely with my neighbor above.

A friend of mine who formerly worked as a mechanic at the local Dodge dealership has told me frequently of owners of late model Rams with Cummins engines still under warranty who brought their truck to the service department with a complaint of high oil consumption, blue smoke, etc.

My friend told me the first thing they did was pull the top off the air cleaner box. If they found an aftermarket filter, K&Ns were his "favorite", they simply voided the warranty and called the owner to come get his truck. A replacement or reman Cummins engine comes with a high price tag.

We live in cotton farming country where the winds blow most of the time, sometimes very hard in spring and fall. Dirt will quickly ruin an engine. The OEM filter prevents dirt intrusion. Why mess with a good thing? The OEM filter was carefully engineered to protect your engine?

Aftermarket filters improve nothing but the seller's bottom line.

Just a few threads down the list of unread posts I was browsing I found another thread on the same topic, different filter, and found Rusty's post linked here.

I agree with Rusty. Each TDR member can read the test results and make his own decision as to what filter to use.

My friend chucked his after finding fine dust in his turbo and that's here in Urbanville(San Diego). I like my stocker with psm type downtube and the 9946 NAPA(Wix).

There isn't a better filter than OEM for the stock box.

 

[Grizzly]

That's what I have always preached, there's nothing better than the OEM paper air filter.



My son, who has a 04. 5 Dodge with a Cummins and an NV5600 called Geno's today to order filters and a a few other parts. They (Geno's) tried to convince him on getting the Airaid filter, which they say is better than the K&N. I told him no, stick with the OEM paper filter. After some time and I couldn't convince him on the OEM filter, I told him I was going to start a new thread and ask the experts. Most of the opinions support the OEM.



I just spoke with my son, who is a TDR member but doesn't post because he's too busy with his construction business and his DW and two sons. He is now 100% convinced on the OEM paper filter.



Thanks for all the response.

I just installed the Mopar 4" paper filter ordered from Geno's Garage. Funny thing was, I had an awful hard time getting the airbox cover back on afterwards. It seems that the rubber strip around the top edge is thicker than my old filter. I had to take the air tube off the rear side and align the cover such that I could push all the fingers into the holes at the same time, then force the other side down enough to get the holding clips back on. It was quite difficult, but eventually I got it closed up.

Has anyone else run into this problem? I even called Geno's to make sure I had the correct filter, which they assured me I did. I believe the same filter fits all '03-'09 models.

 

[Prairie Dog]

You know, I've read that from several posters on other forums regarding the 4" being hard to install but mine just slipped in easily. Either some boxes are a little different than others or maybe it's the brand issue - I used a Wix.

 

[Regcabguy]

In all fairness to the Airraids,I believe the construction is much better than the old ones.



Concerning the fit of the new OEM's,my 9946 fits great.



I was formerly using an AFE PG7 oiled one. That was a bear to get on. I was afraid that the clips might break. I used the PG7 for 20K and always had great oil reports.

I wonder if this fit issue has anything to do with the differences between the 5. 9 and 6. 7 lower housing. There is a step in the housing to clear the pleats and the 6. 7 housing required this step to be made deeper into the housing to clear the deeper pleats. A 6. 7 filter will fit the 5. 9 housing at the top but the pleats will hit and jam a bit part way down. I believe that there is a specific part number for a deeper 5. 9 filter that comfortably fits the 5. 9 housing so beware that this specific filter and the stock 6. 7 filter are not exactly identical.

A tight seal isn't a bad thing, and since you don't have to open the box to check the filter status its not a common issue.

When Amsoil releases their 4" EAA the OEM will get a run for its money, but until then my truck has the OEM. . of which air is the ONLY OEM filter on my truck

Personally, I went back to the stock box after 3 years and getting sick of dealing with the filter and seeing dusting inside the intake tube. I went to the stock box and added a toilet bowl mount flange to the bottom of the box, ran 4" black pipe down with a 45 degree elbow positioned so that it hangs about 2" below the air dam. I did this last fall and I may tweak the amount the elbow hangs down. if you pick the correct flange, a threaded black cap will fit into the top side of the flange with just the right amount of friction and stay put. You won't need to worry about this part as I use this cap in the winter. So far I have better flow than I every did with an oiled filter with their box, I used to be able to turn up the chip and make the over head consul chime telling me to service the air filter. With the stock box and plumbing, it doesn't sense enougth restriction to trip the computer. All the parts amounted to maybe $35 from the local hardware store. It's comforting to know that the air is being filtered to what Cummins set as a standard.

I have noticed a little more smoke on acceleration with the stock over the AFE but I am staying with the OEM.

prairie dog, j pul said it best on the 5. 9 to 6. 7 filters. before the 4" 5. 9 filters became available we tried to mod our 5. 9's to accept the larger 6. 7 filter. when that did not work i started watching the threads and when someone posted of changing his 6. 7 box i pm them and bought enough of them to convert all of my 5. 9's to 6. 7 boxes. about three months after the last conversion wix came out with the deep pleat for the 5. 9. but it is nice just to stock one filter.

 

[Prairie Dog]

Ah, that explains it!

You're exactly right. I took some snips, and after measuring the difference, I cut a small angle on the pleats so that they would clear the step in the housing. After that, it slips right in. It still fits real tight, can't see how it would compromise the filtering ability, seems fine.

 

[JMetzger]

I wish I could get that 4in filter to fit my 02 with out major modification but I guess it is for 03 & up.

I have one of the early third gen filter minders that would suck down with a purely stock eng. For those of you that don't remember, Dodges fix for this was to install a less sensitive minder rather than free up the air box's ability to breath. I kept the sensitive one and found with the Air Raid, it wouldn't move at all. I also never found any of the "dusting" some people talk about and UOA's always came up clean.

With the 4" Wix replacement, the FM moves only slightly even with the Smarty on it. So I'd say the new paper pleat is definitely a keeper.
