NGK 24399 OE Type Wideband Air/Fuel Ratio Sensor 5-Wire 18mm Oxygen Sensor

The NGK (NTK) 24399 is an OE type wideband air/fuel ratio (A/F) sensor, also called an oxygen sensor or O2 sensor. NTK is a leading supplier of original equipment oxygen sensors. This sensor is built to match OE fit, form and function.

A wideband sensor gives the ECU a linear output signal. The ECU can tell exactly how rich or lean the engine is running. It uses that information to keep the air/fuel mixture close to stoichiometric. This supports good combustion, lower emissions and better fuel efficiency.

Key Features:

• Direct-fit 5-wire wideband A/F sensor design
• Heated sensor for fast light-off
• 18mm thread diameter with 7/8" (22mm) hex size
• Wire length of about 40.5" (1029mm)
• Factory-fitted OE type connector, water-resistant, for easy installation
• Planar zirconia ceramic sensing element with a dual-coated platinum interface for fast response and durability
• Contaminant-resistant overcoat helps protect the element from poisoning
• OE development includes vibration and thermal shock testing
• Cross-reference numbers: OE 1588A228 and 234-5051

A new NTK oxygen sensor helps restore proper air/fuel control. This can lower emissions, improve fuel mileage and engine efficiency, and extend catalyst life.
