Description

NGK O2 25605 sensor for the 2000-2005 Volkswagen Passat 4-cylinder 1.8L, the 2002-2004 Passat W8 4.0L and other vehicles reads the oxygen in the exhaust and sends the ECU the feedback it uses to help control the air-fuel ratio. The readings also help alert OBDII systems to possible fuel delivery or catalytic converter efficiency problems.

Heated narrow-band sensor using switching zirconia technology
Vibration and thermal shock testing during development, plus testing during manufacturing
Water-resistant connector and harness accessory hardware for easy installation
3-stage contaminant-resistant plasma jet and deposit trap overcoat protect the ceramic element against poisoning
Dual-coated platinum interface and thinner ceramic element for quick light-off and response times
