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.

THESE 2 FILTERS WERE UNBELIEVABLY EASY TO INSTALL ON MY 2007 5.7 LITER SR5 TOYOTA TUNDRA. I'VE NOTICED A DIFFERENT TONE TO THE SOUND OF MY ENGINE. I NOTICED A CHANGE IN THROTTLE RESPONSE. I DEFINITELY WOULD RECOMMEND K&N FILTERS AND WILL USE THEM IN THE FUUTURE.

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.
