AFE drop-in filter

[elamb]

I'm not looking to start any wars. Considering drop-in filters I mostly read about K/N drop-in filters pros & cons. I would like to get some pros & cons on the AFE drop-in. Like does it fit good in the factory air box or anything else you guys could add.



Thanks,

Eric

The AFE drop in is a very high quality air filter, nice framework and rigid filtration media



I ran one as a test

the AFE systems are great. Their install is simple and there is no drilling or modifications that are needed in order for them to fit. They are a great product.

I think the lip that seals the airbox is better on the AFE than the K&N. A little thicker and softer.

I have the drop in AFE. It seals great in the oem airbox. One side on my filter that has the metal grate pulled out of the rubber, but doesnt affect the sealing in the box. I cleaned mine the other day & put the stock back in to let the AFE dry & noticed the turbo sound was almost non-existant compared to the AFE. My egts were also around 50° hotter with the stock filter.

Thanks for all the replies guys. I guess one of the main things that make me nervous with these filters is me. :-laf Is hard to screw up on cleaning the dern thing? Mainly oiling, too much or not enough.



Thanks again

Filters

Elamb,



Consider the Pro Gaurd 7 AFE's they stop a the dirt the 4 layer gauze don't, in fact AFE has specs that show paper fitler dirt stopping specs for the PG7's. It's the only filter we distribute just for those reasons.



Cleaning is no real big deal, back flush wiith water apply cleaner let soak back flush repeat as necessary. Re oil after it dries totally and go to the truck for installationl. A lot of folks worry about over oiling, it's no big deal the engine eats it and burns it like diesel, now if you had a gasser it would be a problem as it can effect Mass Air Sensors etc.



Call us if you need and other question answered.

Thanks for the info. Mark. I may give you a call when I figure out what I'm going to do.



Thanks,

Not trying to start a war or argue but I must point out a few things.



I disagree with Mark on the over oiling.



The ISB engines in our Dodge rams also use a mass air flow sensor. Also in the air stream is a Air Intake sensor, either one could be screwed up by oil on them and send wrong signals to the ECM.



Oil on the inside of the intercooler is also not a good thing, air to air cooling would be compromised considerably if enough oil coated the inside of the intercooler.

Filter Oil

Ron,



You are correct about the sensors, however to fill up the intercooler with oil or change the operation of a sensor in

a turbo equipped vehicle by over oiling the filter you would have to reoil it every 1000 miles or less and the filter would have to be dripping with oil when you installed it. The turbo runs so much air thru the system as compared to a naturally aspirated gas engine that any oil is run thru so fast the sensors never see it. Even the Fords with the crankcase ventilation system dumping directly into the turbo intel tract don't fill up the intercoolers hardly at all.

Mark,



You sound like marketing tactics to me.



I never said fill the intercooler with oil. A film of oil on the inside will impead what the intercooler was put on our trucks for in the first place.



Secondly, Make a search on the TDR and you will find guys who have had sensor problems due to debrie on the sensors. I was one of them, although it came from a K&N filter and was probably due to me over oiling it, the problem still exists from over oiling an oil type air filter, guys have reported filters direct from the factory that were over oiled. I also experienced gunk on the turbo blades. Since I have removed the reuseable type filters I have not had to replace a sensor or have I seen gunk on the turbo blades, the same as before I used the reusable oil type of air filters.



With that being said I think some of the reuseable types are fine filters as long as they are properly used for their specific application and maintained properly.



All this is from my personal experience and other members here on the TDR. Use the information as one wishes, I know what type of filter I will continue to use in the future.

Didn't Cummins release something about not recommending people use oil type filters? Specifically because of turbo related failures due to debris collecting on the fins?

Filter Oil

Ron,



Again your right, if it has happened to you obviousley it can be a problem. What I wanted to express is not that you claimed your intercooler was filled with oil, but that to get enough oil in the intercooler to effect it's charge cooling capacity would be pretty tough to do unless the filter was dripping with oil etc. The intercooler is pretty large surface area and to have enough oil in it to change it's performance would be a significant amount. To get oil to coat the turbo blades especially at the engines operating temp and at the rpm it spins would also have to be a large amount of oil introduced to the intake at one time. Not trying to argue with you, I have been toying with these diesels since 1985 and have not ever seen these problems unless the filter is drastically over oiled. That was the question that elamb asked and I was responding to. No offense.

Mark,

Thanks for clearing that up.



Just trying to level the playing field by letting people know problems can and do exist for varying conditions.
