I have had an Amsoil for a couple years. Air duct is always clean. Slightly louder than a stock air cleaner, probably nowhere near as loud as a K&N. Flow should be more than enough for a BOMBed engine.
The best and first mod to free up the intake should be to remove the air duct to the fender. This increases the intake noise a bit-I put my turbo silencer ring back in.
It also allows more airflow. When I installed my new, severly over oiled Amsoil filter, I could still pull the filter minder down almost 1/2 way. When I cleaned the filter at 24,000 miles, I could still pull it down. Removed the air duct and now it won't budge.
You will probably get posts from some people concerned about drawing (heated) engine compartment air but I read a post where someone stated warm air is better than not enough air.
I would like to hear if anybody running a clean stock air cleaner that can pull the minder down has tried removing the duct.
The K&N users I have talked to cannot pull the filter minder down until the filter is very dirty.

A month ago when I went to Dubois Wyo to pick up my 4" exhaust from Jerry Jardine,we got to talking amsoil filters and Jerry told me he has seen these filters (the foam part) cum appart and get in the engine and cause some serious problems,He also told me the only (other than egt) bennefit of the KN was longjivity. he said the dino can prove this,spool up time may not be as quick also,he said if you are not dessert racing than you really dont gain much.
after market filters are a highly contrivial subject and you will get as so many oppinions that you wont know what to do,about the only thing I can say is find what works for you and also do oil analisis,look at your silicon reading that's the dust that slips by.

Sounds like round 1 for another heated Amsoil vs K&N argument 
#ad
For the past 2 yrs I've been running the Amsoil, prior to that the K&N. I had no problems with either. According Amsoil thier filter is more effiecient and out flows K&N. Ask K&N and they will say the same about thier filter, adding "Amsoil's independent comparison tests are inaccurate". Each has its pros and cons. From my experience I can say the K&N is easier to clean and re-oil. On the down side for K&N, I did not like the grease seal needed between the filter and the air box lid to ensure a good seal (was a real PIA to clean-up when servicing the filter). Amsoil needs no grease seal.
Both of these filters are good filters. I think the key thing of importance for good performance is to properly service the filter. Under-oiling or over-oiling either filter will cause problems. And as mentioned earlier the Amsoil Filters tend to come over oiled when new, therefore you need to dab off some oil with a lint free cloth. If the filter minder shows a restriction then dab a little more off and keep repeating until you are no longer able to pull a restriction.

I've had the Amsoil filter for about 2 years now. I clean and reoil about 1-2 times a year. The fit is great, can't see light through it, like many claim with the K&N. Personally I think either one will work fine, and neither one is really necessary. I do like the Amsoil is oiled foam, where the K&N is oiled guaze. And no sealing grease with the Amsoil. Besides, the Amsoil is slightly less expensive.

2000ney, that K&N flows more "dirt" is pure BS! I have had my OE style K&N air filter element installed for the better part of a year now in my Air Bulldog air filter housing base (using the OE air filter housing top). I also just received my latest oil analysis back from Blackstone... silicon was 1, that's right, 1 (one)... last time I had 4 which is about one half of the tested average. OBTW, did I mention I have to travel down a . 5 mile, dusty (in the Summer) dirt road? Kind of blows the K&N theory about stopping dirt out of the water.
I just through away my Amsoil air filter and put another one in. Had 70K miles on the first with lots of hard pulling. Filter never cleaned infact never opened the housing to check the filter. Never moved the Filter minder even towards the end(I can with stock filters).
I did have a high Silicon reading with a K&N but though the problem was caused by me always opening up the housing to check the filter. I now watch the filter minder... THEY DO WORK! Otherwise I just check the turbo blades and incomming tube but leave the airbox closed.
When I took this one out the entire filtering surface was coated with a oil/dirt/bugs/weeds layer that could be picked off in chunks. Still flowed air to pull 35psi boost and silicon was still in the low teens which is normal for my engine.
I through it away considering the cost of a new one and the hassle to get this one cleaned.

Had a K&N untill the fires filled our valley with heavy smoke last summer. Found the turbine impeller full of ash. Threw the K&N away, installed the Amsoil filter. Results: no ash/dust/crud on the impeller. Removed the air horn too; a little more air box noise, but the "whoosh" sound when accelerating is addicting. I would not put a K&N on my lawn mower. If you can provide enough air flow to suck ANY filter past the screen on the filter, call me. We'll be millionaires!

I've run K&N's, AMSOIL & paper filters on everything except my lawnmower. Only because I couldn't find any for it. So before anyone jumps on me for picking a favorite. I'm impartial to each kind. I simply have opinions about all of them.
Best way I can put your question into perspective... is on a scale of 1-5.
5 being the best, 1 being the worst.
Filtering ability: K&N=1, AMSOIL=3, Paper=5. Air flow: K&N=5, AMSOIL=3, Paper=1.
The basic design of a filter is to "restrict" certain matter from entering the motor.
As filtering ability increases, so does restriction. To my knowledge, no-one has defied that basic principle.
Naturally the opposite holds true.
Additionally, I think its fair to state that we are dealing with CFM ratings and Filtering ability based upon the dimensions of the Rams air box. A paper filter CAN be made to flow AS MUCH air as a K&N. Only it may require 2 to 3 times the amount of filter media to do so.
That may present a problem, when trying to figure out how you are going to stuff this 3'x3' filter into your air filter box#ad
So the real question here is what do I really NEED?
Unfortunately I don't have a universal answer. Your habits, requirements & operating environments differs from mine. So who am I to tell you what you want or need.
IMHO:
The example of driving on a dirtroad with a K&N isn't ideal, unless this was done behind another vehicle. Having done miles of both, I can tell you that your filter will look quit different after following someone... than if you were the only one on the road.
ANYWAY, in very simple terms... It doesn't take a rocket scientist to figure out, If you can "see" through the element... some % of dirt is getting through. NOW, the next question is, is that "good enough"? Will that create a problem?
Frankly, for most who never venture far off pavement. . Its my "opinion" the answer is yes. Considering the breathing advantage. . Especially on Bomb'd trucks. I think a K&N is fine. None of my engines have every developed problems due to running K&N's.
For the guy driving on the Alaska pipeline. I'd probably tell him to leave the K&N at home... and bring a spare paper filter.
So why did I switch to the AMSOIL filter? Well, I've been doing more dusty dirty travel lately and felt I wanted a little extra protection. Did I need it? I don't know. But the bottom line is that I feel better knowing its there... so Yes it was worth the change.

Here are some pictures of the Dodge/Cummins application using the Amsoil air filtration.
System has 129,000 on it, and element was cleaned every 25,000 miles. All oil analysis reports showed no more than 19 ppm (Si)Silicon.
