2010-2017 Tundra 4.6L V8 E85 Flex Fuel Conversion Kits
Boost Your Horsepower by up to 12% with Ethanol
In 2010, alongside the 4.0L V6, Toyota introduced the 4.6L V8 which produced 310 HP straight from the factory. This truck was popular with workers that needed a reliable and powerful truck to haul tools and materials to and from job sites, as well as the weekend warriors and simply fans of Toyota Trucks. Being a 4.6L, it manages to get decent gas mileage and is a real “can-do” kinda truck for the money. Those looking to give this laborers’ dream a little extra get-up-and-go are in luck because our E85 conversion kit for the 2010-2017 Tundra 4.6L can increase your horsepower by up to 12%.
No tuning required!
