Removing the O2 Sensors from an Aston Martin DB9 V12

The Aston Martin V12 engine has eight (8) O2 sensors (a.k.a. Lamda sensors, Oxygen sensors, HEGO sensors). The V12 is in my 2005 Aston Martin DB9 Coupe as well as other models like the DBS, V12 Vantage, Rapide, and Vanquish. Access is very limited, and in this video I show you how to get them out for service. The V12 has four (4) primary catalysts, and each has an upstream and a downstream sensor.
