I have used K&N air filters in all my cars, both performance cars and our family cars. Each car always got better mpg than before the new filter. I have gotten as low as 1.4 and as high as 3.2 increases. They other great thing is the cost savings. We keep cars for longer periods than most people (ex 1997 Lexus ES300 10 years 138K) so the cost savings is much greater for me.
