I received my new intake in less than a week. Installation was a breeze and the instructions were perfect. I installed this intake on my 2011 Tundra with the 5.7L V8. My main goal was to improve gas mileage and my efforts were rewarded. I've noticed my biggest mileage gains in city driving (almost 4 mpg) and 2 mpg for highway driving... once your done having fun with your new toy. Sounds awesome, but not annoying. My ride to work is 400 mi/wk and this intake will pay for itself in less than a year. Recommend this product 100%.
