  • The 2006-2013 Corvette (C6) has the ability to run E85. But your stock fueling system will be maxed out or need an upgrade to support 100% E85 depending on your modifications. Talk to your builder/tuner for suggestions on what they want to see to make this application work to it's fullest extent. In many cases up[graded injectors will be a requirement.
  • This kits harness uses OEM connectors in tandem with OEM products. Fit and finish look 100% stock under the hood. A Chevrolet Corvette (C6) will pick up 10-30rwhp depending on the tune and application.
  • Note: While our flex fuel sensor can be installed and works perfectly fine to run pump gas with your Corvette without a tune, to run E85 your car must have a tune to run E85 fuel. DO NOT INSTALL & RUN E85 WITHOUT A PROPER TUNE. Make sure your tuner has verified your sensor is hooked up and reading the ethanol content before adding e85 to your vehicle.
