Comments about K&N Replacement Air Filter:

I really like this filter. It was used in my KIA Optima LX-2.4 cyclinder. Easy to install. The filter appears durable and of high quality. I can see and feel a difference in how my car drives as well as the positive impact on my gas mileage. I would certainly purchase again. In fact, I have purchase others of the type for all of my household vehicles. I like the fact the I do not have to change the air filter as often as I had been doing with the other air filters I had been buying. I think the benefits definitely out weighs the price.
