Install this Plug-and-Play E85 Kit and Experience the Difference on the Road and at the Pump

Ever since the first horseless carriage was designed and hit the cobblestone roads of the local villages, people have altered, improved, and upgraded them to meet their different needs. The need for improved stability added the fourth wheel, the need to haul heavy cargo added a large cargo area and 4 horsepower engines, and the need to deliver bread and other baked goods gave us our first tonneau covers. Today’s vehicles have 700 horsepower and heated steering wheels, so we know what you’re thinking when it comes to these new vehicles – How can I increase the horsepower? – E85 flex fuel will increase horsepower and improve the overall efficiency of your vehicle.
