Amsoil Drop in filter...well sort of

I received my amsoil drop in nano filter. It basically works, but there is a small amount of fin interference on the short side of the airbox, where the wheel well starts. The overall dimensions are perfect though and sealing to the airbox is great. I also removed the charcoal filter and cage.

As to performance gains I cannot even start to say because these snow tires are so damn squirley, the car is much slower in general. I ran some calibrating runs with the Gtech, and the most I can hit is .61G on launch. I may have to swap wheels again this next weekend and hit the dyno for confirmation of any gains.

here are the pics.

here is the product much will copy
AMSOIL Ea Air Filters represent a major breakthrough in filtration technology. The revolutionary nanofiber technology used in AMSOIL Ea Filters captures more dirt, holds more dirt and allows better air flow than conventional air filters. AMSOIL Ea Filters improve engine performance and help engines last longer.

Absolute Efficiency
AMSOIL Ea Air Filters are the most efficient filters available to the car/light truck market. Ea Air Filters’ synthetic nanofiber media removes 5 times more dust than traditional cellulose filter media alone and 50 times more dust than wet gauze filter media. AMSOIL Ea Air Filters have a service life of 100,000 miles or four years, whichever comes first.

Better Air Flow
AMSOIL Ea Air Filters allow more airflow than filters that use cellulose media alone. Cellulose fibers are larger than nanofibers, and have larger spaces between the fibers, causing contaminants to load in the depth of the media and plug the airflow path, which results in higher restriction and less capacity. The synthetic nanofibers in EaA Filter media have submicron diameters and small interfiber spaces, which result in more contaminants being captured on the surface of the media and lower restriction.

More Capacity
AMSOIL Ea Air Filters hold up to two and a half times more contaminants than cellulose air filters. Since the nanofibers in the media are so small there are more pores per square inch, allowing for higher dirt-holding capacity and lower pressure drop when compared to cellulose filter media alone. Thinner media fibers produce more uniform pore size distribution, improving the filter’s overall quality and ability to capture and retain particles. Testing shows that Ea Air Filters hold 15 times more contaminants than a wet gauze type filter.

Cleanable - Longer Life
When cleaned according to AMSOIL specifications and used in normal service, AMSOIL Ea Air Filters are guaranteed for 100,000 miles or four years, whichever comes first. EaA Filters remain effective for 25,000 miles or one year before requiring cleaning. This coincides with the AMSOIL 25,000-mile/one-year motor oil drain interval, adding even more convenience for motorists by consolidating routine maintenance. (See below for cleaning instructions.)

AMSOIL Ea Air Filters hold 15 times more dust than a wet gauze type filter.

AMSOIL Ea Air Filter media removes 5 times more dust than traditional cellulose filters and 50 times more dust than wet gauze.

AMSOIL Ea Air Filters provide superior air filtration for vehicles in the auto/light truck market.

EaA filters should be cleaned every year or 25,000 miles, whichever comes first. Carefully remove the filter from the housing. Clean the housing with a shop towel, being careful not to knock contaminants into the air inlet. Filters can be cleaned by carefully vacuuming the filter media on the dirty side, or by holding the filter with one hand and carefully blowing the filter media at a 45 degree angle on the clean side using low-pressure shop air (15-20 lbs. psi).

Service Life
AMSOIL Ea Air Filters are guaranteed for four years or 100,000 miles, whichever comes first. The guarantee applies only if the filter has been serviced according to AMSOIL recommendations. In off-road, frequently dusty or other severe duty applications, clean and change more often as determined by operating conditions or as indicated by restriction gauge.

AMSOIL Warranty
AMSOIL warrants that its filtration products are fit for use according to AMSOIL’s recommendations and warrants its products to be free of defective materials, design and workmanship.

nice work figs, improved sound or throttle response?
The car is much louder when the charcoal filter is removed. Like I said, these tires suck so bad I cannot comment on performance other that initial throttle reponse seems more jumpy, but there are also areas of the power band that seem flatter, so I need to see what the dyno says about both the flap mod and this filter. The two stage intake may help low end torque quite a bit...too bad it sounds so awesome.
AMSOIL makes the best product on the market for sure and that is why I run in all my cars. I have there Air Filter, DOT4 Brake Fluid, 0w-30 Signature Series Synthetic Oil, and Synthetic Trans Fluid in my IS F. Tell you what, I can tell a difference with performance and gained a mile a gallon. Gas isn't cheap so the product ends up paying for itself in some time.
Hey Fig is there a model number or something you can hook me up with to make it easier? I want to replace mine and didn't see a model number on this page, maybe I just missed it :)
I am not at home so I will get the number. I am an amsoil dealer and usually offer them at 10 over cost.

+5HP, +5TQ compared to my previous dyno

Part Number

What is the model number on the filter... I think I want to drop one in my car as well... thanks for the pics!
EAA233 I could do free ship, its $35. I am not sure if my vendorship applies from
Fig, Thanks for the information but I am a bit confused?

Is the AMSOIL filter a direct drop-in replacement for the OEM IS-F filter or only one meeting the same measurement specs?

And secondly, did you remove the OEM charcol portion "just because" or did you need to due to the added thickness of the AMSOIL filter over the OEM?

Sorry to be so basic but I'm just needing a little clarification if you would be so kind?
I removed the charcoal filter because I see no need for it. The amsoil filter drops in except for the lower corner where it is too thick. So the media gets crushed a bit in that corner.
What is teh thickness difference on the K and N?
what's the difference between amsoil and k&n?
The Amsoil is completely Dry, no oil to get on sensors etc. The Amsoil uses a nano filtration technology to keep filtration high as well as efficiency. When its clogged, you simply blow it out with a vac or shop air. No washing, no grease.
Check your PM shortly Fig :)
Thanks for the quick and informative reply Fig. Not sure >

what the thickness difference is on the K&N as they are not out yet. I'll let everyone know when then get back to me. May have to try one of the AMSOIL ones on your reccommendation.
How hard is the install? Just couple screws and your done?

I don't even think its screws, it looks like simple clips :)
two clips...however it is much easier of you remove the macaroni noodle tube as well.

Nice description, now you have made me hungry.....:p
haha, its lunch time, you still gotta wait an hour.
