The importance of using a paper air filter

[MChrist]

Thanks Bob I sometimes wonder about my stock box with the thick element in it. We have dust most everyplace our drive is dirt/stone the roads are cinderd all winter then dusty in the summer until the rains. Just dont know what to use really with stock HP.

BIG, in those conditions, I would only use stock.

The oem does an excellent job at stock power levels and has a very high dirt holding capacity

I should add if I had a stock 6. 7 I would only use an oem air filter to be sure of the correct air flow

The second gen air boxes just don't flow enough for a performance app,the later boxes did see some improvements

 

[BIGNASTY]

Thanks for filter info STOCK IT IS.

So my 2011 will tell me when it is getting restricted?

 

[Bob4x4]

Personally I would not wait for the air filter warning. While the filter will continue to do a good job filtering it will loose some flow

The stock box with the fleetguard filter works fine for me. I have added a 4" black sewer pipe on a toilet flange bolted to the bottom of my air box and it goes down to the underside of the bumper and has a 45 degree elbow and a set-up rubber fitting to act as a funnel to help it catch more air and create a possitive air pressure on the intake side of the box. Back when I used the edge juice, I could turn up the power with the AFE stage 2 filter and cause the ECM to give the clean filter warning. When I when back to the stock box with the ram air, it wouldn't trip the service filter warning. That tells me that the deep OEM filter flows pretty good air, at least with a little positive pressure feeding it. I got sick of dealing with the oiled filter as it seemed to dryout way to often and the oil film and dusting on the intake that resulted from it made me trash the AFE. I have also added an RV dump valve to the ram air down at the bumper level so that I can just reach down and close the intake off it is going to be raining and also in the winter when I don't want any cool air help. As well I have a piece of aluminum sceen between rubber fitting and the pipe to keep the critters and leaves etc. out. I sleep better knowing that the engine is getting clean air. It looks lower in the picture than it realy is. It is only about 3" below the air dam on the bumper.

The Gen IV ecm will set a code in memory if a woman other than your wife rides in the front passenger seat.

Luckily she will have to have a high dollar scanner to find that in the history

You need to extend that "T" handle to inside the cab so you can open and close on the fly depending on weather conditions.

I have actually been researching electric RV dump valves and am considering getting one for that reason. When I'm driving in the summer and it sttarts to rain I always stop to shut it and that is a pain in the butt. If I put an electric one one, then I just have to flick the switch in the cab. May end up being one of my winter projects.

It would be nice but for 90 bucks I WILL OPEN THE DOOR AND GET OUT SHUT THE VALVE AND GET BACK IN many times free.

Irrc the2013 Ctd may come with a computer controlled system along those lines

No may it WILL!

Lately, I've been seeing the thinner 5. 9L CTD filters being sold as filters for the 6. 7L. The correct 6. 7L air filter is around 3" deep, whereas the smaller units are about 1" deep.

 

[AH64ID]

The 5. 9 filter was redesigned in 2009, to a 4" pleat version. It retains the same efficiency rating as the 2" version, but with higher flow is longer lasting. IMHO there isn't a better filter for the stock air box.

Just to be clear, Mopar diesel filters are Fleetguard.

The 2" version was a Fleetguard, I do not believe the 4" version is. Fleetguard does not offer a cross for it, and they did for the 2". That alone doesn't indicate mfgr, but I have made some phone calls and done some reading and the 53034249AA is not Fleetguard.

Last I checked Baldwin Filters are all made right here in the USA and they make an air filter for the stock 6. 7 airbox. Now if they would just come out with the fuel filter for the 12's Their fuel filter for the 05 was 5 micron not the 10 or 7 micron that dodge used...

 

[AH64ID]

I talked with Baldwin today, and they source their 4" 5. 9 filter from another manufacturer. They couldn't tell me who.

Just got another oil analysis back and my silicon level was 3ppm again (has been for over 140,000km) yep that oiled K&N is doing pretty good!
