📜 Confirmed Fitment Guide (Delphi EFi Only)
📅 YEARS: Primarily 2012–2020 Delphi EFi systems.
❌ WILL NOT FIT: Carb models, Sentec ECUs, or older Mitsubishi/Daewoo systems. Check your connector size!
Always use anti-seize compound on the threads of the new sensor. This is a critical step to prevent the sensor from welding itself to the exhaust pipe from heat and rust!
🔧 Fitting Tips
- Verify Before Ordering: Due to Hyosung’s varied history with ECUs, please email us a photo if you are unsure of your fitment.
- Order Quantity: V-twin bikes like the GT650R and GV650 use two sensors. Add two to your cart if needed.
- Torque Correctly: Don’t overtighten the sensor into the exhaust bung; use the recommended torque spec to avoid thread damage.
