The A-Premium Upstream Oxygen Sensor is a high-quality OE replacement part designed to ensure optimal fuel economy, emissions control, and engine performance for a wide range of Honda and Acura vehicles manufactured between 2009 and 2015. Positioned before the catalytic converter (upstream), it accurately measures the oxygen content in exhaust gases, allowing the ECU (Engine Control Unit) to fine-tune the air-fuel ratio. This helps maintain emission standards and extend catalytic converter life.
