Van-a-goners:

Does anyone have any suggestions for improving the quantity of air that can be sucked into the 2.1L WBX engine? I am using the K&N filter in the stock box. I am looking for an inexpensive way to increase the flow down the tube that sticks up into the passenger side rear air intake vent area. Any ideas?

Does the drivers side rear air vent have any purpose other than cooling the engine with a chimney-like action? 

Thanks,

Josh
