Solved the idling issue I have had for years with my 07 Ford Explorer. I also noted a fuel mileage increase almost immediately. Thank you!

This is the second KN filter I have purchased. I am very pleased with my purchase as I can readily feel the improved acceleration and improved performance with my Explorer.

I mainly purchased this for ease of maintenance,but also your great reputation, I've heard your guy on the Car Dr. radio show with Ron Ananian several times. I do like the way it improved my V6 2008 Explorer, nothing dramatic, but I've had it since 10/07. It definitely improved performance. I would recommend it.

Great product. This filter works great! This is my 4th K&N filter. It pays for itself many times over the life of the filter and provides improved performance.

I purchased this Air Filter Because the advertisement said it would improved the gas Mileage, It did not.
