Product Description
Car Oxygen Sensor MR578634/MD345850/MR507385
Original Equipment Lambda Sensor compatible with Mitsubishi, Chrysler, Dodge, and Volvo vehicles
Product Overview
These Original Equipment (OE) Lambda Sensors are manufactured for Mitsubishi vehicles with cross-compatibility across select Chrysler and Dodge models. The OE numbers MR578634, MD345850, and MR507385 are frequently cross-referenced together across multiple vehicle platforms.
These 4-wire heated sensors monitor oxygen content in exhaust gases and relay information to the Engine Control Unit (ECU) to maintain optimal air-fuel mixture for efficient combustion and reduced emissions.
Important Note: These OE numbers are grouped as direct interchange references, but cable length and connector details may vary between manufacturers. Always verify your original sensor's connector shape, cable length, and position before ordering.
