Oxygen Sensor Air-Fuel Ratio for Lexus IS300 2001-2005

This oxygen sensor is a precision air-fuel ratio (lambda/O2) sensor designed to restore and maintain optimal combustion for the Lexus IS300 years 2001–2005. Built by IWOKPHD, it uses a heating-type, magnetic induction design to reach operating temperature quickly, delivering accurate readings to the engine control unit (ECU) and helping your vehicle run cleaner and more efficiently. With the correct part numbers—89465-53110, 234-4015, 8946553110, and 8946553200—this sensor is a direct, reliable replacement that fits seamlessly into your exhaust system. Origin: Mainland China. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.

Main Description

Installing a fresh oxygen sensor is one of the most effective ways to improve fuel economy, reduce emissions, and maintain engine performance. This sensor provides real-time feedback on the exhaust’s oxygen content, enabling the ECU to fine-tune the air-fuel mixture for each driving condition. A healthy sensor helps prevent rich or lean mixtures that waste fuel, trigger unnecessary emissions, or cause rough idling. For the IS300 (2001–2005), this part delivers a dependable replacement that restores the precision the factory system relies on.

Key design points include a heating-type element for faster warm-up and magnetic induction sensing for reliable signal generation. These features reduce sensor lag after startup and contribute to smoother acceleration, steadier idle, and better catalytic converter efficiency. With CE certification and a two-year warranty, you can feel confident in both performance and coverage after installation.

Trust and reliability are built into every InterCyprus purchase. Since 2002, intercyprus.com has been a source customers rely on for genuine parts that meet strict standards for fit and function.
