Well u can see the plugs are different. Notice the wires on GEN 2 are quite puny compared to GEN1? And Gen 2 wires arent wrap with conduit.
To reduce the stress that may be exerted on the "puny" wires and to protect the wires. I added a conduit and tape it to the plugs directly.
The O2 sensor looks the same, less the marking on the sensors itself.
