Amsoil Oiled Foam>???-Opinions?

Well Spicer, due to the sincere spirit of your test, and the additional comments you've offered---I ordered a couple AC-Delco air filters. I will shelve the Amsoil foam. I would suspect the difference felt will be ZERO.

I had a K&N at one time, but I didn't like the construction quality. Strangely---I never felt the 15 horsepower they promised, by just droping their filter in>???

My gut feeling is that flowing more air (AND DIRT!) may have some apps, at WOT for racing. For daily drivers, even say...Firebirds, I don't think it "works". And...seems filtering is still the most important job...for a FILTER.

I never felt the horsepower increase either. Maybe if I waited until my old filter was almost plugged I would have noticed a surge in power.

After going back to the Amsoil 2 stage filter using the Amsoil filter lube my mileage dropped about 3mpg.The construction is great the filter is working well but the mileage is why I took it out before.This time I will stay with it till the end of the year.I plan on a 600 mile drive this week and hope the mileage improves. I wonder if paper is that much better than foam when it comes to mileage. I admit I was worried about the MAF sensor but the car runs great.It does seem that the dealer would have you believe that their filters work best for their cars.The thread about the Hundyi oil filters a example.To me the proof is in the overall results.

Anyone else out there? This is a good thread that we should not let die!!

I'm very happy with my Amsoil air filters. I run them on 4 Pontiac Montana vans and Si in my UOA's has always been extremely low. Washing them is a bit of a pain and they do tend to leave a bunch of filter oil in the airbox but it wipes out easy enough. Paper filters arn't cheap anymore so I probably break even pretty quick.

Several years ago, before the new re design, I used the Amsoil filters in several cars. After one fell apart I went back to paper and stayed there as the UOA actually improved in terms of silicon when I went back to paper. Just too much of a hassle to deal with even if they did fitler better.

If you look in the archives, you'll also see quality control issues with the original Amsoil foam filters. Some had situations where the foam deteriorated!

Yep, some of the AMSOIL foam filters deteriorated. In most cases, at least in my experience, the most failed in GM cars, accompanied by bad EGR systems.

The one in m 1985 Volvo 245 turbo wagon fell apart after some 13.5 years. ****!!

With the new line of filters, at least for some 45 applications, this won't be a concern in the future.

I noticed that my filter minder was tripping about 1/3 of the way with the AmsOil foam filter ('05 Cummins!). Then I found Spicer's filter test and got worried about dirt getting into the motor. When I pulled the intake tube off the turbo, it had dirt in the mouth of the turbo

!!
I ordered my self an AC Delco paper canister to install instead. A little time will tell if I see any more dirt down there.
I do think the dirt problem is worse on the turbo diesel's. But don't think a normally aspirated gasser is immune. I have an old Int'l p.u. that I put a K&N filter on. After reading Spicer's filter test, I pulled the lid off of the air cleaner and found dirt inside the air horn on it's carburator.
I'm not telling you all to switch to paper. But, if you care about your vehicle; check the intake and see what kind of dirt is getting in there. You might find a leaking seal or something......
(Or you might be like me and just get rid of the 'high flow' and go back to paper)

A foam 2-stage or 3-stage filter, 'properly oiled' with the 'proper foam filter oil' will work better than anything in the widest types of conditions. end of story. As I read it the problems arise when someone 'thinks' . foam filter oil is very thin and runny for a reason. dip it completely in then squeeze not wring out very thoroughly. then let air dry. the agents that make it runny evaporate leaving a extremely sticky stringy type goo. thats what works and thats the only type of oil that should be used. something thats super sticky and thick will not cover properly and will actually run out and thru very fast leaving a huge mess and no filtering ability. so.... use what you should use , dont think and be happy with a foam filter. its no mistake that 95% of all racing vehicles use foam. best over widest area.... sounds similar to my initial statement..... paper sucks.....literally, in water or with methanol. wet paper flows near zero. nuff said. K & N.... I hate them, but I still use them... why? cuz on a sprint car and with minimal amount of time they can be run with least hassle and time consumption, if its dry at all I built a foam wrap that goes around all 4 you'd be amazed at how much dirt a 1/4 " foam will hold.

For several years I ran the Amsoil oiled foam air filter. My UOAs showed high silicone and Blackstone Lab recomended I check my air filtration. Recently I just decided it wasn't worth the trouble of keeping it washed and oiled so I replaced it with a NAPA Gold paper filter. I may try one of the new Amsoil EA air filters, but I think I am done with the oiled foam. It looks to me like Amsoil is dropping the oiled foam filters and replacing them with the new EA filters.

My own 96 Cherokee gets either Napa Gold or Purolator paper filters and the silicon values on my UOA's are pretty low. Don't need to be trying to convince myself that this or that will supposedly increase my horsepower. My engine has plenty of power already.
