Xero Limit Flex Fuel Kit - BRZ/GT86 - Rear O2 (13-21)

Thanks to this flex fuel kit you can use ethanol without worrying about the mixture!

Our kit fully uses AN fittings with no need to cut the stock lines, a Zeitronix ECA with sensor/plugs/harness, fully plug and play ECU harness using evap or the rear O2 signal.

For most USDM vehicles select the Nylon fititng/hose version for easiest installation and cheapest option. 6 AN Braided Hose for best appearance/durability, and we also have a JDM option for those with JDM vehicles that utilize hose/clamps and not the quick EFI fittings.

Requires tuning. While we do not guarantee the factory fuel system will be compatible with ethanol on any vehicle, we have not had any reports of failure in more than 10 years and hundreds of kits in circulation. 

Please note that while this kit works with both 13-16 and 17-21, please select which years below so we can pre-wire it for the correct year.

For off-road use only, this kit utilizes the rear o2 input that can only be tuned for race-only cars or those not subject to US emissions laws.
