"I noticed an increase in pep as soon as I installed the filter. I then proved it by running 0-60 times. My Subaru Outback LTD sedan used to get there in 10.5 seconds, but now I get to 60 in a neck breaking 9.5 seconds.
As for gas mileage, it's hard to tell. The weather has gotten colder so my gas mileage always drops, plus I suppose I've been a little lead footed lately with all the power.
It's only been two weeks, but so far, so good." —John P from Oak Forest, IL bought a K&N Air Filters for a 2001 Subaru Outback.
