First thing i do when i purchase a vehicle is replace the filter with a k&n Love to hear the sound of the extra air rushing in to the engine when i step on it....Defenitly ITS the first item i replace when i purchase a vehicle...Been using K&N for many yrs...Love the sound of the air rushing into the engine when i step on it...For sure a increase in power and response...Its worth the extra money as it pays for itself due to never having to buy another air filter....

I put these filters on both of my cars -- an Mercedes and an Kia Minivan -- the engines on both cars are running smooth- they have good pickup and mileage is a little better. I am quite satisfied with these filters.

Great product

This product truly lives by its words! I have noticed difference in my car's performance and gas consumption. I would recommend it to any person who wants something of high quality. It was also really easy to install and took me about 5-10 minutes to install.
