Air Fuel Ratio Sensor for Renault Captur, Clio, Megane, Twingo

The Air Fuel Ratio Sensor for Renault Captur, Clio, Megane, and Twingo from IWOKPHD is a precise upstream oxygen sensor designed to keep your engine’s air-fuel balance in check. Positioned at Sensor 1 in front of the catalyst on the exhaust manifold, this sensor continuously measures exhaust oxygen levels and feeds real-time data to the engine control unit to optimize combustion. Compatible with a range of Dacia and Renault models—including CAPTUR, CLIO, MEGANE, TWINGO, and related versions like DOKKER, DUSTER, LODGY, LOGAN, SANDERO, SMART FORFOUR, and 453 FORTWO—you’re getting a reliable replacement that helps restore peak performance and efficient fuel use.

Key benefits include improved idle stability, smoother acceleration, and better fuel economy by maintaining the correct air-fuel ratio. When the sensor performs correctly, your catalytic converter works more efficiently, emissions are reduced, and your engine runs cleaner. This makes it a practical upgrade for vehicles showing signs of degraded oxygen sensing, such as fluctuating RPM, rough running, or reduced MPG.

Benefits & Tips

• Restore precise air-fuel control to improve idle quality and throttle response after installation.
• Support better fuel economy by ensuring the engine runs at the optimal mixture across city and highway driving.
• Replace as part of a regular maintenance plan to keep exhaust diagnostics accurate and the catalytic converter protected.
