AEM Dryflow

[md_lucky_13]

Very impressed with this filter.

High quality build. Looks like it will filter better then my current setup.

The heat shield is every bit as top notch as the filter.


I would never consider owning an oiled filter, and I have built several intakes that use paper filters..

I'm replacing an intake with an open element paper filter for the AEM unit.

Isn't it ironic that on a forum called "bob is the OIL guy", that you want a filter without oil?

I like the design of the dryflow filter as well.

I just bought one as well and am extremely impressed. It even had the "new filter smell."

I have had one on my Ram 1500 5.7 with a K&N FIPK since March. After 4K miles, I took it off and inspected the inside of the tube and it was very clean. Just a slight coating of really fine dust, like baby powder. I did not experience any difference in millage or performance, but I like the fact that I was able to clean it with a degreaser and not have to oil it like a K&N. I never had a problem with the 3 K&N filters I have run on different vehicles in the past. This just seems to be a lot easier.

You know.. That brings up an interesting point..

This is installed on a 2001 Dodge Cummins Diesel.. This is only one addition to a fairly extensive list of upgrades on the truck.

What I found was interesting was the EGT levels I have been recording. I found it was fairly easy to pull the egts above 1200 pre-turbo (hot hot hot in a diesel) on flat ground, full throttle with my old setup..

I do NOT beleive that an air intake is going to change much.. maybe a small difference, but nothing noticable.

I'm starting to beleive otherwise.. I have noticed that my EGTs are not reaching 1200 at all, no matter how hard I rod the truck..

I don't have any "evidence" other then experience that this is happening.. I just know what I usually see for EGTs, and what I see now.. It made a difference of at least 100 to 200 degrees.


I have wanted to purchase one of these systems since the very first day it came out.. But it somehow always got knocked to the back of the list. Well, what a mistake I made. I'm extremely happy and I should have done it sooner.

anyone have any test data on how well these flow/filter yet?

 

[biomed_eng_2000]

The reports on the AEM website state that they filter better than the competitors and flow 40% worse than the competitors for a given pressure drop.

“Many of our competitors emphasize flow as a primary means of power production in intakes,” stated Chief Engineer John Concialdi. “While flow is certainly an important part of the equation, we find that tuning the inlet to work with the harmonics of the engine produces the best power gains. We address flow in the sense that the engine requires a given amount of flow, so we calculate our filter size to exceed this flow requirement to accommodate potential future engine modifications. This allows us to retain a high level of filtration efficiency and still exceed the flow requirements of an engine. Our filters will trap more dirt, and consequently extend the life of the rings and seals in your engine.”

"While flow is certainly an important part of the equation, we find that tuning the inlet to work with the harmonics of the engine produces the best power gains."

All true, but I doubt there product does anything to maintain intake resonance either.

That's what makes these $35 ebay/$250 AEM "filter on a stick" systems so great...
-if you want higher flow, you can slap on a $40 K&N filter.
-if you want better filtration, you can slap on a $40 AEM filter.

interesting. I may pick up one of their filters if they offer it in a size that will fit..

so far i am happy with my dryflow also, but do any of the cotton filters also have a built in velocity stack?

 

[biomed_eng_2000]

I would estimate that 90% of all name brand aftermarket filters have some type of velocity stack. Maybe 40 years ago the concept of a velocity stack was new, but now, it's so common that most companies have it but don't even bother to mention it.

Maybe a tad off subject, but for these AEM dryflow filters they recommend cleaning them with ONLY that detergent sold by the manufacturer. Unforunately it runs about $10 per cleaning. (Kinda expensive for a simple, liquid cleaner, would ya say?) So I'm wondering if we can just use isopropyl alcohol or liquid dish soap instead of that magical $10 cleaner you get off AEM...any thoughts?

 

[PRND3L]

At 20k miles recommended cleaning intervals, $10 doesn't seem so bad.

But I'm really cheap!

Ya see, it's not that $10 is too much, it's that $10 is too much for a cleaner.

 

[PRND3L]

I hear ya' Chuck. I had posed the same question back in May to no avail. I'm just too chicken to experiment for fear of wrecking the filter.

 

[biomed_eng_2000]

The AEM dryflow is made of polyester. Get a cleaner that will not damage polyester and you'll be fine. I gather since many clothes are made from polyester that most clothes washing detergents will work just fine.

Fill a 5 gallon bucket full of water and dip it in and out several times without letting the neck of the filter drop below the water line.

That removes almost all of the dirt in the filter. Let it air dry, and you are ready to go.
