Saving fuel nowadays is so easy. With a T57KI80 Tornado fuel saver in your 2006 Toyota Tundra, you will surely achieve an improvement in your fuel mileage. The primary purpose of having a fuel saver is to help the vehicle acquire a better fuel economy. As an essential component of the Tornado gas saving devices, this fuel saver effectively saves gas as it increases the miles on every gallon therefore improving the fuel economy and enhancing horsepower at the same time. An auto channeling tool that generates a swirling air motion, the Tornado fuel saver allows the air to move faster and more efficiently through whirling air around bends and corners. It causes better fuel atomization that leads to an increase in fuel economy anywhere from 7-24%. This was proven by road testing done at an emission lab licensed by the EPA. Dyno testing also shows an increase in horsepower, around 4-13. Another great thing about the Tornado fuel saver is that it is very easy to install. Installation will only take 2-5 minutes and it requires no regular maintenance. A Tornado fuel saver will work in either carbureted or electronic fuel injected engine. It is made of stainless steel and it is composed of meticulously engineered slotted fins that convert the normal air intake flow into a powerful spinning vortex of air which then blends the fuel and air together to provide better fuel mileage and performance as well.
