Honda Motorcycle/Marine Oxygen Sensor 35655-ZY3-C01 35655-ZZ5-004 Direct Replacement

If your Honda motorcycle or marine engine experiences idle instability, acceleration weakness, high fuel consumption, or the engine diagnostic light is on, the oxygen sensor has aged or failed; it normally provides real-time AF signal to the ECU to maintain optimal combustion. This is a direct replacement oxygen sensor, OEM numbers 35655-ZY3-C01, 35655-ZZ5-004 and 40203-00; fits Honda motorcycle and marine series. Installation must be performed with a cold engine to avoid burns; use a dedicated wrench to tighten to prevent thread damage or seal leaks.
