NGK NTK 25505 OE Type Oxygen Sensor O2 Sensor Direct Fit

The NGK NTK 25505 oxygen sensor (also called an O2 sensor or lambda sensor) is an OE-type direct-fit replacement. It monitors the oxygen level in the exhaust stream and sends that data to the engine control unit, which uses it to keep the air/fuel ratio correct. A worn or failing sensor can raise fuel consumption and emissions, so replacing it helps restore efficient engine operation.

Key Features:

• OE-type design that matches the fit, form and function of the original equipment sensor
• Dual-coated platinum element for longer service life
• 3-stage element overcoat that protects against contamination
• Fast light-off times that help reduce emissions and improve fuel economy
• Pure alumina ceramic that filters exhaust gas
• Waterproof, factory-fitted connector for a proper fit
• Built by NTK, a major original-equipment supplier of oxygen sensors and part of the NGK family

A new NTK oxygen sensor supports lower emissions, better gas mileage, stronger engine performance and longer catalytic converter life.
