Walker 273-10009 Exhaust Gas Temperature (EGT) Sensor

Walker Products EGT Sensor for Audi and Volkswagen

Walker Products 273-10009 is an exhaust gas temperature (EGT) sensor built for direct replacement in select turbocharger applications. It monitors exhaust heat at the exhaust mount location and uses a 2-wire, blade-terminal design with a black female connector and D-shaped housing for a precise OE-style connection.

Compatible With 2009-2012 Audi Q7 and 2009-2012 Volkswagen Touareg, this sensor supports accurate exhaust temperature feedback for vehicles equipped with the T3 before turbocharger setup. The Walker Products line focuses on engine management and fuel system components engineered to meet or exceed OEM standards.
