NGK NTK Oxygen Lambda Sensor OZA544-N4

NGK NTK Oxygen Lambda Sensor

NTK is the world's largest manufacturer of oxygen sensors. The NGK NTK Oxygen Lambda Sensor is designed to maintain optimal fuel efficiency and is supplied with a direct-fit connector similar to those used by the OEM manufacturer for easy installation.

Every NTK Oxygen Sensor undergoes a complex three-test process, including long life, high temperature, and anti-poisoning, to guarantee high quality and durability. As future emissions standards become tougher, NTK is further developing oxygen sensor technologies to help provide cleaner, more efficient engines.

An oxygen sensor continually detects the oxygen content in the exhaust gases of an engine. The oxygen sensor output signal informs the vehicle's ECU (Electronic Control Unit) whether the AFR (Air-Fuel Ratio) is lean or rich. Based on this, the ECU adjusts the amount of fuel injected into the engine to achieve an optimal AFR.
