NGK 21524 NTK Oxygen Sensor O2 Sensor Direct Fit OE Type

The NGK 21524 oxygen sensor (also called an O2 sensor or air/fuel sensor) is an NTK OE-type direct-fit replacement. It measures the oxygen content of the exhaust gas and sends a voltage signal to the engine computer. The computer uses that signal to adjust the fuel mixture for efficient combustion and low emissions.

Key Features:

• OE-type replacement designed to the same fit, form and function as the original equipment sensor
• Dual-coated platinum element for longer life and fast response
• 3-stage element overcoat helps protect against contamination
• Fast light-off time helps reduce emissions and improve fuel economy
• Pure alumina ceramic filters the exhaust gas
• OEM-specified connector and attaching hardware for straightforward installation

NTK is the world's largest supplier of original equipment oxygen sensors. A new sensor helps restore accurate fuel control and can help prevent the higher fuel consumption and emissions that come with a worn sensor.
