"I am not sure how it is will work in long run but more air easy access to engine should be a plus. I used before this filter it save me money on gas plus got me more power. I have new car with 5.6 L v8 I am not sure what to expect. Need to take it for long ride to see difference. But in general I like it product. I will recommend since more and easy air means more power and less gas on mile." —Oleg L from Brooklyn, NY bought a K&N Air Filters for a 2011 Infiniti QX56.
