 Amazing product. Added 3 more mpg. Gave my throttle a crisper response. I am saving to buy a K&N cool air intake because of how impressed I am with just the performance of this one life time filter. So thank you for an awesome product.

 Worth every penny. Did a 1800 mile trip to South Texas and was averaging 33.2 mpg hwy and noticed some slight performance increases. Highly reccomend this product.
