Declare your independence from foreign oil and unleash the power of ethanol!

FLEX-BOX SMART KIT™ is an easy-to-install system that lets you operate your vehicle on any combination of ethanol and gasoline. So you can fill up on E85 (which is a premixed blend of 85% ethanol and 15% gasoline), E20, E10 or pure gasoline. There’s nothing to set, nothing to adjust. FLEX-BOX SMART KIT™ does it all!
FLEX-BOX SMART KIT™ will be available for many current-production and older cars and trucks and high-performance racing engines. And since FLEX-BOX SMART KIT™ is on its way to EPA-certification, your vehicle’s warranty isn’t affected.
FLEX-BOX SMART KIT™ is a compact unit that mounts in your engine compartment. It continuously monitors your engine’s emissions, then delivers supplementary fuel injection to allow your vehicle to operate at optimal performance — no matter what fuel blend is in the tank.
With FLEX-BOX SMART KIT™, you can choose your fuel based on performance, price, availability or your interest in caring for the environment and reducing dependence on foreign oil. FLEX-BOX SMART KIT™ gives you freedom of choice!
