The big hilclone thingy would be to swirl the air and maybe seperate dirt/water/foreign matter from the air stream...
My air filter has a plastic case covering half of the element with fins on it which swirls the air as it moves past.. does the same job.
Does the factory setup take air from behind the headlight?
If you didnt go offroad you can run a pipe into the front bumper to receive colder air (Like the rice boys

).. but the difference is negligible, in both power and economy. But offroad, this would be more drama than it's worth.
The best way is a snorkel... and then u have a better offroad setup if you ever do venture out
If you stay on road, you could fit a K&N or Uni Filter. These give better flow and performance, but are known to let more particles through... Do a search on these items if you like.
If you really want to do it... buy some flexible pipe and be creative.... It wont make too much difference though... Its no sports car
