A few months ago I purchased an O2 sensor for my 2011 SHO. The sensor said it was compatible with my car but when I plugged it in, the car said the heater was malfunctioning. I could not figure out what it was until I compared the two sensors. What I ended up finding was that when we bought them, O'Reilly sold us the sensors for vehicles made from 02/2011, not up to 01/2011. So, if you need to buy sensors make sure you get ones according to build month/year.
