Product Reviews

  The best way to get an air filter is online. You told me the correct one to order, set the price and shipping. I had it in no time. Why did I buy a K&N filter? Well, I am lazy. Back in the 1950's my dad would have to re-oil the filter in our Chevy every so often. I can not remember the interval. Finally cotton filters came into being. They were the greatest thing since sliced bread. Once a year, every 10k miles. Now we are back to oiled filters. And now I only have to get my hands greasy, and knuckles busted once every 50k miles. I do not notice HP increases. But I only change about every 50k miles. Just an old guy I am, and want to enjoy driving, not be kept prisoner by changing filters.

  Filter arrived within 3 days of placing order. installation into my 2011 Chevy Tahoe took no longer than 6 minutes. My Tahoe runs stronger, smoother & sounds healthier. My gas milage jumped up by almost 2 mpg. could not be more happy with the result of this up-grade.

  I put the new filter in my 2015 Chevrolet High Country truck. I could not be happier. I have used K&N filters in all of my vehicles over the years from Corvettes, trucks, motorcycles. I will always use your products. Thanks.
