High Durability: Iridium is six times harder and eight times stronger than platinum, allowing it to withstand the extreme temperatures of high-performance engines without degrading. Applications and Compatibility Whether you are a DIY mechanic or just

An oxygen sensor, also known as an O2 sensor, measures the amount of oxygen present in a vehicle's exhaust gases. This information is used by the engine control unit (ECU) to adjust the air-fuel mixture, ensuring that the engine operates within an optimal range. The oxygen sensor provides critical feedback to the ECU, allowing it to make adjustments in real-time to minimize emissions, improve fuel efficiency, and optimize engine performance.
