I purchased this air filter for my 2014 Tacoma. I have a 4 cylinder and wondered how much difference this filter would actually make. I have to say I am very impressed. Not only do I feel a slight increase in power but the engine has a more aggressive throaty sound to it now which I love. I haven't have the truck long enough to compare MPG's but I am quite happy with the performance of it. Will definitely recommend.
