Not only a power boost but money saving. You will get approx. 10% more mpg. Also no need to buy another air filter for 100,000 miles. This filter pays for itself and more. A must have for any vehicle!!!!!!

Pretty amazing. Noticed the difference immediately. Car is more responsive to throttle. Can't tell about gas mileage yet. Having a hard time keeping my foot off the gas.

I always install K&N filters in my cars at the first air filter change. They are a value and performance enhancement that cannot be beaten, and I would recommend them to anyone. Auto Anything blew all of the other suppliers away with their price!!
