Customer Feedback

I wanted to let you know how happy I am with this filter! I didn't buy it for a power increase, it's my commuter car. I have a 1999 Saturn SL1, 1.9SOHC and 5 speed. After an engine swap, I ran a new name brand filter for about the first dozen tanks. Mileage was an average of 31.7 mpg. After changing to a K&N filter, I noticed an improved mileage of 33.4mpg over 3 tankfuls. Thinking something must be wrong perhaps my math, I put in the Name Brand filter. Mileage went back down to 31.7! OK, I'm sold! Thanks again for your awesome product.

I work in auto parts and have always endorsed K&N for power and improved airflow, but now I'll add the economical advantage of the filters to those who may not otherwise think about that.

Thanks again,

K&N Filters on a Saturn - I own a 92 Saturn SL1 with 140,000 plus miles on it. It has always been a freeway driver averaging about 34-35 MPG. 38 MPG has been the most on long 200+ mile trips when the car was new. I recently drove up to Reno, Nevada from the Bay Area and was astounded at my next fill up. It averaged 46 MPG!!! The car feels like it has as much power or more than when I first bought it. 46 MPG, I am amazed. Every car I get from now on will have K&N filters.

Thank You,

My car is 15 years old and still had the factory fuel filter on it so I'm excited to say I've gone with the performance enhancing filter by K&N, along with other items to help improve the performance of my Saturn. Easy installation. No hassle. Will shop with you guys for other vehicles I should happen to own.
