Flex Fuel Kit

Our flex fuel kit collection offers everything you need to unlock the benefits of high-ethanol fuels like E85. By enabling your engine to run on blends from pump gas up to 85% ethanol, you can take advantage of E85’s naturally high octane rating and intense intercooling effect, often making it the easiest way to add power and knock resistance on boosted applications.

Flex fuel conversion typically involves these key components, and many kits in this collection bundle them for a complete solution:

  • Flex fuel sensor with integrated ethanol content and temperature output
  • Plug-and-play wiring harness for factory-like integration
  • High-flow fuel injectors to meet the increased volume demands of ethanol
  • Upgraded fuel pump and lines for consistent fuel delivery
  • Engine management calibration or flash device to adjust fueling and timing maps based on ethanol content

When choosing a kit, consider your vehicle’s current fuel system capacity, engine management compatibility, and whether you need a complete package or individual components to supplement existing mods. From daily drivable flex fuel conversions to full-race E85 setups, you’ll find options from trusted manufacturers ready to ship.
