I'm really happy with these new air filter for my Honda CR-V. I don't notice any gas fuel savings so far, but when stepping into the gas pedal, the engine delivers more power with less pressure on it . I really like the feel of driving my SUV on the highway, and I don't mind if I don't have a fuel saving, performance is just way better. Thanks

To me K&N air filters always has been great products to purchase. It last longer than (brand name) filters or other cheap filters. I use K&N oil filters and air filters in all my cars I had owned. I do highly recommend it too anyone.
