NGK NTK 25154 Oxygen Sensor O2 Sensor Direct Fit OE-Type

The NGK NTK 25154 oxygen sensor (also called an O2 sensor or lambda sensor) measures the oxygen content of the exhaust stream. It sends that signal to the engine computer so the air/fuel mixture can be kept in the right range. A fresh sensor helps lower emissions, supports fuel economy, and helps protect the catalytic converter.

Key Features:

• Sensing element made from NTK ceramic material with an integrated heater. It reaches operating temperature in seconds, which gives faster closed-loop activation and lower cold-start emissions.
• Platinum-coated element for durability, with a protective overcoat against contamination.
• Corrosion-resistant housing protects the ceramic element from silicone and lead poisoning.
• Porous PTFE filter lets atmospheric reference oxygen in while keeping water and engine contaminants out.
• Built to OE standards and tolerances to help with smog-test compliance.
• Every sensor goes through a 3-test process to check quality and durability.
