Product Reviews      Review part E-4425

 After years of throwing away OEM filters twice a year I now have a better filter that will last for many, many years and allow me to clean it providing better airflow to the engine. K&N quality is second to none with perfect fit. Money spent on K&N products is an excellent investment in increasing the performance, longevity and owner experience of whatever product it is installed in. Thank You K&N! Five stars simply because no more were offered!
