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.

The new filter fits great. It was a drop in and go.
