Default Re: 2009 H2 gas mileage improvement?

what about a cold air intake system? they are like $400-$500 from K&N. Is it worth the money. Maybe since i drive 75 mph most of the time, it just is what it is.....Yeah - I know, slow down. ain't gunna happen. you go slower than that in LA and you get run over.
