Key Features

• Stainless steel construction for exhaust-system durability
• Metric thread type for EGT sensor service
• Direct replacement bung for rusted or damaged sensor ports
• Weld-on plate included for exhaust pipe repair where needed
• OE FIX solution for targeted repair instead of full pipe replacement

Detailed Description

Dorman 904-457 is an Exhaust Gas Temperature (EGT) Sensor Bung Repair Kit built for repairing the sensor mounting area in the exhaust stream.
