 Great products.
Chris, Houston, Texas
 I have used K&N filters in my LandCruisers for many years. They are great. It also seems that my gas mileage has improved which is a help since my vehicle doesn't pass a gas station it doesn't want to meet.
Jim Hill, Houston,Texas
 I have not used the filter yet as the old filter is still good. I am sure it will be fine as everyone that has one likes it.
John Jones, Massachusetts
 I am very pleased with the product I purchased also the shipping and handling time it took for delivery.
Oswald Sheather, Hawaii
 It was easy to change and fit like a glove. I discovered I had a clip not hooked up so I fixed that. I seem to have more power and the mileage indicator says it went up about 1.5 miles per gallon.
Roger Herder , Oblong, Illinois
 Just as advertised. Provides more power and increased gas mileage. This is my 5th K&N filter for vehicles I own and have owned. What can I say except, I am a K&N filter believer! Fantastic product!
Dave Forcey, Bakersfield, California
 My 2012 Toyota Tundra (5.7 liter V-8) was getting about 18 mpg and on rare occasions 19 mpg.  I replaced the stock air filter with a K&N air filter. MPG is now a steady 20 mpg.  I have used K&N air filters in other vehicles I have owned and have seen an improvement in mpg. K&N web site is easy to navigate, so give them a try.
