Love the delivery. Ordered Tuesday before noon, received next day. Product is drop in ready. Fairly easy to clean ( takes a bit of time to dry. I use a paper one as the K&N dries ) Gives the car just that little extra power for no money. I also use the oil filters by K&N.

This product is superb / excellent. My 2016 Acura RDX AWD became more responsive and added few more horsepower. My engine can breathe more freely. And you can really feel the difference. I highly recommend K&N Air Intake Filters to everyone. Try it and you will never ever say goodbye..

I put this replacement filter in my new 2014 Acura RDX, gas mileage has improved by 2 to 3 mpg.<br /> This is around town don't do much highway driving. I know it would work well because had one in my 2010 RDX it did same on gas mileage. Keep up the good work your filters are the best thing since apple pie.
