Have you actually tried an after market intake on an h3? There is definitely a noticeable difference in power including holding speeds and downshifting.

There is another question as to air filters though and that is if the engine need more air. I think the H3 performs better with the additional air flow after switching back and forth between a K n N and the OEM filter.

Also, I read somewhere(have to look around) that oil gauze filters pass like 99% of the dirt in the first 3% of the filter life. So I wouldn't install an oil filter right before going off-roding in the desert. On a recent trip I replaced my OEM Filter for the trail.
