Just bought a used Mazda and put a K&N in the airbox and cleaned throttle body. Runs better and pulls harder especially under load. About 1 mpg improvement in gas mileage consistent across three full tanks of fuel by measuring. Easy to install and perfect fit! Mark, Raleigh, NC

Hello, I am very impressed with the K&N Air Filter that I purchased for my Mazda 6. The fact that the filter is covered for 1 million miles is impressive. I don't mind cleaning the filer opposed to filters that you have to throw away after 15,000 miles. I am very happy and look forward to buying another K&N air filter for my Nissan Frontier soon. Thanks, Matt
