Since installing my K&N air filter I have noticed an increase in gas mileage. Being an 11 year old vehicle I was skeptical that just an air filter could improve gas mileage but it has. I am getting approximately 1.5 more miles to a gallon. I also like that fact that recommended cleaning is every 50K miles. You have to purchase the cleaning kit but if you consider that you will never buy another air filter, and get better performance this is a no brainer. Buy it from AutoAnything, not K&N.
