Help! I have the 2011 Roadster if that makes a difference. I installed the filters, removed all the airbox parts, but once I removed the side panel, I was lost. I can't find the O2 Sensor or O2 Eliminator. It doesn't quite look like it does in the pic. Also, what do you do with the sensor that was plugged into the exhaust pipes where you put the oil plug? It's just gone with no mention of what to do with it... Please help
