Honda OEM (14-26) TRX420 Rancher Oxygen Sensor 36531-HR3-A22

Genuine Honda OEM NGK Oxygen Sensor 36531-HR3-A22 is designed for select Honda Rancher, Foreman and Foreman Rubicon ATVs. Also called an O2 sensor, this factory replacement component monitors oxygen in the exhaust and sends information to the engine control system to help maintain the correct air-to-fuel mixture.

A failing oxygen sensor may cause poor engine performance, increased fuel consumption, irregular idle or a stored fuel-injection trouble code.
