Oxygen Sensor for Renault Captur A4535420500 Upstream Lambda Air Fuel Ratio Monitor

Upgrade your Renault Captur’s engine management with the upstream oxygen sensor A4535420500 from IWOKPHD. This high-precision O2 sensor sits upstream, directly in front of the catalyst, continuously monitoring exhaust oxygen levels to help your ECU regulate the air–fuel mixture. The result is cleaner emissions, steadier idle, and improved fuel efficiency across city and highway driving. Designed to respond quickly to changing exhaust conditions, it helps your engine run more smoothly and reliably, especially during cold starts and rapid load changes.

Designed for broad compatibility, this sensor supports a range of Renault and Dacia models, including Dokker, Duster, Lodgy, Logan, and Sandero, as well as Captur, Clio, Megane, and Twingo. It is also compatible with Dacia Smart ForTwo 453 Fortwo variants. With its upstream placement and robust construction, this part is a practical replacement that sustains your vehicle’s performance and compliance with modern emission standards.

Key features include a magnetic induction sensing element and a heating type build, crafted to withstand the engine bay environment and deliver consistent readings over time. The sensor is manufactured for reliable performance and is offered here as a direct replacement part for the specified models and part numbers A4535420500 and 4535420500.
