Oxygen Sensor Upstream for Honda and Acura RSX 2.0L CR-V 2.4L Element 2.4L Heated Piezoelectric

Upgrade your Acura RSX 2.0L and compatible Honda/Acura models with an upstream oxygen sensor designed for 2003–2011 Honda CR-V 2.4L, Element 2.4L, and Acura RSX 2.0L (manual transmission). This heated, piezoelectric O2 sensor provides precise feedback on exhaust oxygen levels, helping your engine control unit optimize the air-fuel ratio for cleaner emissions, better idle stability, and improved throttle response. Replacing a degraded upstream sensor can resolve rough idle, reduced fuel economy, and hesitation, restoring smooth acceleration and consistent performance in daily driving and longer trips.

Key compatibility references include OEM-style numbers such as 36531-PRB-A11 and related variants, ensuring a reliable fit across listed models. The sensor is a heated (4-wire) upstream device designed to reach operating temperature rapidly, so your engine runs cleanly and efficiently from the moment you start the car.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.

Benefits & Tips

• Faster warm-up and stable fuel trim: the heated O2 sensor minimizes rich/lean conditions during cold starts, helping the ECU reach optimal fuel calculations sooner.
• Improved drive quality: expect smoother idle, steadier acceleration, and better throttle response once the sensor is functioning correctly.
• Simple diagnostics and maintenance: replace a failing upstream sensor to pass emissions tests and reduce catalyst stress from imperfect air-fuel mixture.
