I'm using a C&L filter for a 04 Cobra Mustang... it takes up about 3/4 of the OEM box and I think costs around $30. And I actually had dyno proven gains from it haha

 

 

I've used the stock PCX003 filter and the K&N drop-in filter off and on over the years. I decided to get away from the oiled reusable filters that you have to apply oil after cleaning and went with the AFE Pro Dry S filter a little while back. I like it so far, but haven't tried to clean it yet. Here it is if you're interested:

There are some users of the oiled cotton gauze filters that do see an increase in the silicon levels on UOAs. The aFe dry filter does have the similar air horn/ velocity stack like the stock part. The also have this mesh that makes the filter media pretty stiff.

 

I use stock filter.

 

considering he wrote that they were throwing out filters after one use, that leads me to believe the conditions were quite severe compared to a city street. k&n is fine

 

How many higher HP s2k's are using the OEM box? None, end of discussion. You should see some of he intake set-ups people run on the H22's. Crazy stuff.

High HP S2k's are turbo/SC'd. You don't have high HP NA S2000's w/o major engine modification that render intake comparisons meaningless. The people that do NA builds are doing it mostly because they love tweaking, modifying, and personalizing- not really with the expectation of significant gains. The intake is one of the simpler mods to do and looks flashier when you pop the hood. Plus, it can have a major effect on the sound of the car, which is another important characteristic to most people.

Being FWD, the location of the airbox for the H22 isn't ideal for airflow, and the flow path is long and winding. Honda didn't take the time to optimize the design and tuning, because they were too busy with the F20. The airbox in the S is front and center with much more direct air flow.

 

K&Ndrop in after 6 years it is nice to not have to pay again and again and it is a snap to clean...a tad more noise and a tad more pickup/less heat bog...nice.
