NTK Exhaust Gas Temperature (EGT) Sensor (91511) RTA9000-EE250: Fits Audi

This NTK Exhaust Gas Temperature (EGT) Sensor (91511) RTA9000-EE250: Fits Audi - is an OEM-quality replacement part and is suitable for a range of vehicles.

Exhaust Gas Temperature (EGT) Sensors monitor the temperature of the exhaust gas, ensuring that exhaust gas cleaning components achieve optimal conversion rates.

EGT Sensors also serve as a temperature monitor for turbochargers, catalytic converters, diesel particle filters, and nitrogen oxide reduction systems. They are used to monitor the optimum operating point, to protect the relevant components from temperature overload, and to keep them in the desired temperature range for optimal conversion rates, thus making them an important component for the reduction of harmful emissions from vehicles.
