AFE Pro-Dry S vs. Amsoil EaA

[Tinman]

I'm looking to replace the air filter on the '06 and want to keep the stock air box. Which one is best for 1) flow 2) filtration. I don't like oiled elements so I'm looking for a good flowing, efficient non-oiled air filter. I like the cone AFE unit for the stock air box b/o the larger surface area, but AFE is known more for flow than filtration effeiciency. What do you guys thinks?

I am not an expert on this but based on what I have read the Amsoil filter will give you the best of both. Yes the oiled filters will typically give you more air with less filtration than the amsoil. The Amsoil filters have a life expectancy and really cannot be cleaned. I do like the Pro-GUARD 7 from AFE and I currently have one in the truck now to see how my oil sample turns out, The oil has always came back good except for little high soot levels (probably from the Smarty and hard driving). It has been in for about 3500mile. I have used the AMSOIL since I have had the truck with good results. Just my 2cents. .

From a filtration perspective aFe states that their Pro-Dry is in between the ProGuard 7 and Magnum. Thus it is not the ultimate in filtration. I think the Amsoil will filter better.



From a flow perspective, the Pro-Dry is also between the ProGuard 7 and Magnum, and I am sure it will flow better than the Amsoil.



FWIW I had the Amsoil nanofiber stock dropin replacement filter and the 4" dryer hose modification to the stock airbox and it didn't flow worth crap. I replaced it with an aFe stage 1 Pro-Dry filter setup and the flow is much better. The EGT's and smoke both dropped when I made the switch. For where I live, I think it is an acceptable compromise in filtration efficiency. If I did a lot of driving on dirt roads I'm not so sure.

The AMSOIL Nano-fiber filters are cleanable. You use a low pressure air gun from the inside and blow out. I also use my shop vac on the the outside to get the "big" dirt off. They are good for 100,000 miles with cleaning intervals every 25,000 miles. I have the EaaU4510 on my truck. I have also installed drop in filters on gas vehicles with no problems. Something to think about is what kind of boost and air flow are you getting. I have a customer with the sled puller 66 turbo on his truck and it sucks the EaaU4510 closed. But, he said that he thinks he bought a filter that was to small. -Jason

I have the 4510 with the prefilter and so far am happy with it. had the progard 7 and the Uni also. The Uni took forever for the EGT to cool for shutdown and the progard got filthy and I couldn't get it clean to my liking, it never turned back to the original color. Don't know if it was a bad thing but just don't like popping the hood and everyone asking if I ever clean my filter.

 

[Tinman]

That's pretty much what I figured. The AFE will flow better but at a filtration cost. The AMSoil will filter better but can only flow so much with a stock sized element. I'd like to get to 450-500hp once I get around to up rating the '06. Just looking for a good clean way to feed the beast. Do you AMSoil guys know if a EaA drop cone element is in the works?

the EA flows great new but within 25,000 mine was pretty much useless. I tried to clean it with shop air and a shop vac with no luck.

I have been cleaning my Amsoil filters with soap (K&N cleaner so far) and water the last few times. I bought two of the 4510 oval cones so I would always have a clean one on the shelf. I have not done an oil analysis since doing this so I don't know if I have hurt them or not but I can't see any harm visually. Air is what is recommended but it wasn't cleaning them that well. I get lots of black water off them with low pressure hose after soaking with the cleaner for a time.

Yup, don't waste your money. Mine lasted 16K miles and no matter how often I ran air compressed air through mine, the yellow air flow meter would be down half-way daily!
Worst money i ever spent... . #@$%!

 

[amsoilman]

DON'T USE water on the EaA filters, or you will ruin the fine NANO-FIBERS that are on the surface of the filter.

I use the compressed air method for cleaning and have had no problems at all.

 

[CumminsPower98]

Air doesn't do the job for me. There is a lot of dirt left and dark spots when looking at the light through the filter. I asked on here one time about using water and no one said anything so I went ahead and tried it. I read somewhere that it wasn't a problem if these got wet. I have yet to do an oil sample since cleaning with water so I will see what that shows. It is a lot of money to spend for a filter if water ruins them and air doesn't clean them good enough.
