Faulty O2 sensor

shouldn't the 02 sensor be covered under warranty on a 2008 model?

or do they have issues with the extensive list of mods in your sig?
 
I got a CEL and it's saying my O2 sensor is faulty, anyone know where I can get a good price on a new one?

Awesome! (ugh)(yupnope)

I will be buying the 2nd o2 sensor because Mazda put it in sideways and when i (meaning 2 friends and i) tried to take it out it was mangled beyond any recognition....the threads that is...
