Hondata CANFlex Flex Fuel Kit for FL5/DE5
Take your performance car to the next level with the Hondata CANFlex Flex Fuel Kit, designed specifically for the 2023+ Honda Civic Type R (FL5) and the 2024+ Acura Integra Type S (DE5). This advanced flex‑fuel system allows your turbocharged 2.0‑litre engine to run pump gas, E85, or any ethanol blend you choose — giving you increased horsepower and torque while maintaining the flexibility to fill up anywhere.
The CANFlex system is 49‑state SEMA‑certified and engineered for stock vehicles (stock intake and exhaust), so you can enjoy performance gains without needing extreme modifications. With the included calibrations integrated into Hondata’s FlashPro Manager software, your engine will run smoother, spool faster, and deliver a more connected driving experience. Whether you’re cruising the freeway or pushing your car on the back‑roads or track, CANFlex gives you more control and more fun.

Performance Benefits
With the Hondata CANFlex kit you can expect a boost in performance over standard bolt‑on upgrades. The system is built to deliver 16‑36 additional horsepower in stock form, and when paired with the Hondata Fuel System you can achieve much higher gains. The kit also helps your turbo spool 200‑400 RPM earlier when running E85, meaning quicker response and more fun behind the wheel. Every time you drive, your Civic Type R or Integra Type S will feel sharper, more responsive and better tuned for performance‑oriented driving.
Because the system supports ethanol blends, you benefit from higher octane levels (100‑105 octane with E85) and cooler combustion — which works like an in‑cylinder intercooler effect and allows more boost safely. Plus, you can switch between regular pump gas and flex fuel seamlessly, giving you freedom and performance in one package.
Upgrade your ride with the Hondata CANFlex Flex Fuel Kit and extract the full potential of your FL5 Civic Type R or DE5 Integra Type S. It’s the ultimate flex‑fuel upgrade for serious enthusiasts who demand more from their drive.
