NGK Mazda 2 2014-2011 Direct Fit 4-Wire A/F Sensor

NGK is the world's largest supplier and manufacturer of OEM oxygen sensors. Oxygen sensors play a critical role as part of the vehicle's on-board diagnostic system in maintaining optimal engine performance, maximizing fuel efficiency and reducing harmful emissions. While conventional switching oxygen sensors only switch rich or lean, wideband oxygen (or Air-Fuel Ratio) sensors produce a linear output signal that allows the ECU determine exactly how rich or lean an engine is running and make continuous and precise adjustments of the air-fuel mixture to stay closest to stoichiometric, providing the best possible combustion and fewest emissions. A ceramics company at our core, uses state-of-the art technology enabling complete control of the ceramics used in our wideband oxygen sensors from raw material to finished product. Trust The Sensor Specialist for full-line market support and OE application technology. This is an upstream Oxygen Sensor / Air Fuel Ratio Sensor for the Mazda 2. It is designed as an OE-style direct fit replacement part for 2011-2014 models with the 1.5L 4-Cylinder engine. It plays a critical role in the vehicle's onboard diagnostic system, contributing to optimal engine performance, fuel efficiency, and emission reduction.
