I've been wondering the same thing. It's the only way to get max power.

Alright here's a pic.It don't look like much but like i said it's for dry conditions and it works.

I don't know if i would chop your only airbox cover to do it,i did because this quad is only for flattrack/tt racing.If anybody wants one made,I have a airbox on ebay and will split it up for $50.Of coarse it would look better than this one.

What mods does your quad have? What map are you running, exhaust, how have you adjusted flowrate and offset, etc...

How does the engine perfrom with your mod? Give us a little more info please!

He has the FX400 cannible version.It is tuned with a mill tool since it has the MC500.The quad is fast and only mod is that pipe and airbox.

Everything's on the dyno sheet.The mixture screw was leaned a 1/2 turn and i leaned the low end a little.Air/fuel was 12.5 to 1.I have that graph also if you want to see it.

I did basically the same mod to mine,cut a hole in the air box behind the steeering stem in front of the gas tank.I took a piece of screen and screwed it over the hole and put a piece of foam over it and left the piece of plastic that covers that area off.It does make a difference.Gaged in a drag race and made about a quad length difference in about 600-700ft.It works for sure but ONLY use in dry conditions.

Thanks to your guys ideas I've modded a airbox lid. I actually found a filter that fits great. Its a perfect size for the lid. Its a briggs + stratton filter part#399877. I wish KN made a replacement filter. I'll try to get a few pics up soon. :usa

K&N Panel Filters

Have you guys checked to see if any of these filters would work? Why hasnt anyone came up with a custom like aluminum airbox yet? why not run two round k&n's up front under the plastic?

Haydug actually has a prototype set up of something like what you are takin about.Maybe he will chime in and answer your curiosity.

Haydug please tell me more about your setup and post pics if u dont mind. It would be nice to make a new airbox design that would work for all riding conditions and work with the 250R conversion.
