Product Reviews    Review part HA-2504

I installed this filter on my Honda CRV about a year ago.  The performance improvements were noticeable right off the bat.  I was hoping for improved mileage, but I went from 26mpg to 21mpg.  I like the throttle response but wish the fuel economy was better.  I give the performance a five star rating and mileage a two star rating.

I just thought I would share this short story with you about a k&n air filter. Aprrox. 3yrs ago I was at the auto wreckers in edmonton alberta looking for a mirror for my old beat up 1990 honda accord. I noticed a dirty oily old air filter laying on the ground underneath another similar year honda accord. It pretty much been parted out . I wasnt even sure what kind of a air filter it was but it looked well constructed so I took a chance on it and bought it from the wrecker for a $1.
When I got home I did some investigation and indeed find out it was a k&n air filter. I kinda compared it to what was in my 1990 honda accord and it looked very similar in size. I purchased a k&n cleaning and oil kit and cleaned it up,dried it out and sprayed it with the oil as per instructions. It came up like brand new. To make a long (sorry) story short I have had this in my car since. My accord has 394000 kms on it and it has never run so good. I used to have an engine light symbol go when it got cold but since I have had this filter in there it has been perfect. It is dec 22/2012 now and I have asked for a k&n air filter for my 2008 toyota tundra 5.7 litre for christmas.  Thanks k&n   and merry christmas
