Cheap and easy intake. Buy a good after market filter. Take masking tape and hacksaw. Remove the filter box, tape if to where it only has about 1" on the filter side of the clamp. Leave the two little prongs on the bottom, then cut that sucker, a little sand paper to smooth out the rough edges and presto a new intake.

 

I've already got that, but I think there is still restriction in that flexible section of the plastic tube.
