Seems to be more acceleration and slightly better gas mileage. Installed filters on a 2001 and 2009 Subaru Foresters. The 2009 shows mpg on the dash display and average mpg. The average is up 2 to 3 mpg on each long trip so far.

Love K&N.

Perfect fitment, great quality, only thing I could possibly ask for is a dry version. But it's a great product none the less.
