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.

I put K&Ns in all of my vehicles. Love the serviceability of the filter instead of just replacing the junk paper filter every 2 years. The only reason it didn't get 5 stars is the fact that I can hear a whistle coming from the air box now with the higher flow.

Put this in my wife's Toyota Sequoia 5.7 as we've had this type air filter in all our past vehicles. As always, I love that lil extra kick.
