On a K-series engine the induction won't switch on the MIL or otherwise cause problems.
The best upgrade is to switch to a K&N or other metal panel filter in the standard airbox, and then, if you want, modify the air intake pipe to the box to be more direct and use a larger diameter pipe (this comes at the cost of ingesting extra grit/rain/small mammals into the airbox).
Cone filters without airboxes make the engine run badly at low engine speed/low throttle openings.
Typical cone filters with cylindrical airboxes have less volume in the air box and lower gap from the filter surface to the air box walls which will force the airflow to bend, so while they look ideal, they may well not be from an airflow perspective.
Panel filters generally favour flow, though of course the standard air box does have the 90 degree turn at the top, so still not ideal.
The ITG filter is probably a good compromise - it has a nice bulky air box, so plenty of volume, and a reasonable gap between the filter and the side walls, as well as a large flat area towards the intake end.
