First of all, I purchased two K&N Air Filters. One Cabin Air Filter and the other Air Intake Filter. The Cabin Filter, I should have purchased sometime ago. It is well worth paying for it and having the ability to wash it and reusing it over and over is a no brainer, in terms of saving money. The Air Intake Filter, saw a low end increase and definite fuel increase. Again, the idea of washing and reusing the Filter is a definite plus.
