What's the best set up for air filteration?

What do you guys recommend is the best set up for a new air filter system? I'm thinking a K&N Air Filter with an outerwear screen instead of the airbox lid. But without the air box lid, I don't think the filter will stay in place properly... how do I get around this? Has anyone tried this setup? Do most people also use an outerwear pre filter on the K&N filter itself in addition to the screen in place of the air box lid? Or is it a better idea just to get the lid vents? Any help is greatly appreciated, as I'm a noob to this kind of stuff.

Edit: looks like there's an adapter kit from pro design... one comes with a foam filter and one comes with a k&n... which do most people use?

YUP!! k & n and all fabric filters flow more air and also let ALOT more dirt by, oiled foam is the best way to go to protect your engine, the extra hp gains by using a k & n are going to cost you with more frequent rebuilds

Best flow, K&N, but you need to keep them clean and oiled properly, I have ran these for 20+ years with no problems in MX, sand, dusty... but you have to keep them clean:

For the maintenance impaired, foam:

What are your suggestions for frequency and technique of cleaning and oiling fabric filters like the K&N ones?

I clean it after every ride. Soap and water rinse repeat. Takes 5 minutes then a good liberal oiling the next day and ready to go.

my 06 banshee has the double filter changed over to a single k&n with an outer wear and the lid removed. It's had no trouble at all. And I have over 100 hours with it. The only problem I've had is if you apply to much oil to the filter, the cotton swells up and starves the engine for air.

K&N makes a cleaner and the oil and they suggest how to use it. If super dusty I will clean/oil every ride, most of the time I just inspect the filter and only clean the outerwear(BTW, no lid on mine). Motors last a long time if maintained properly, too clean is better than too dirty. If you think you might lag on the maintenance then I'd suggest foam, but either way a dirty filter robs performance and eats your motor!!

Cleaning a K&N after every ride isn't a good thing. The K&N's actually filter better once they get dirty. Until then, they'll let me dirt and grit through than a standard foam filter.

i ran a open k&N filter due to me adding a yfz 450 rear shock, works great with a jet kit. i did make a bracket to help support the filter and carb
