Description

This oxygen (O₂) sensor is engineered to meet or exceed OEM specifications for Mazda Miata 1.8L L4 engines from 1994 to 2005, including both naturally aspirated (N/A) and turbocharged variants. The sensor monitors the oxygen content in exhaust gases and sends data to the engine control unit (ECU) to maintain the optimal air-fuel mixture for efficient combustion. A faulty O₂ sensor can trigger check engine lights, cause rough idling, reduce fuel efficiency, and increase emissions. Replacing it ensures accurate readings, restores engine performance, and keeps your Miata running smoothly. Made from durable, heat-resistant materials, this sensor features a direct-fit, plug-and-play design for easy installation. Oxygen O2 Sensor for 1994–2005 Mazda Miata 1.8L L4 N/A & amp; Turbocharged.
