No reply so i tried something, make a bigger hole ( cut the flat bottom part ) so if its not working maybe i could duck tape to make the hole smaller.
But now with the bigger hole the Sled bark when i crack the throttle,i also remove prefilter it was clog with oil.

the reason there's no real power gain is you're pulling hot air from the eng bay it likes fresh cool air to make power, ie ram air lid or mod the top of air box with frog skin

This mod looks alot like the Ulmer Racing mod, from what you can tell. The Ulmer airbox get great reviews.
I have a similar cut to this, and also added drilled holes in the front of the airbox, but still under the filter foam. My thought being that it would get the cold air effect.
Does anyone believe that you can have too much opened up ?

You could cut 2 holes in the front pan, run 2, 2" pipe to the bottom of the box.Than put a screen over the holes in the front. As you drive the air flows toward the box by the tubes. Air force induction.

Do you think it is very important to have a power commander on the 2011 Apex with this air box mod????
I've heard that the injection is very lean on the new Apex, so it would be worst with this air box mod....

They run lean in mid range and on top according to dynos and Allen himself. Im going with an airbox mod only when my pcv is in in case i notice something different
