Are o2 sensors for a Z28 or ss the same thats on the 3.4? Does anybody know were to get some, i think its time ti change mine...

 

well i dont know if they are the same...i got mine at murrays so i'm sure you can get them at any auto parts store...i think mine were like 45-50 for both...and i suggest getting the o2 sensor socket....made the job a lot easier....overall not hard to change...increased my gas mileage a bit bc the car had 120k on it and they were stock
