The front Oxygen sensor and the MAF (Mass Air Flow) sensors are 2 different items. The O2 is in the exhaust before he cat and the other is right on the intake.
By A/F I mean Air fuel sensor. I believe this is the one before the cat and the O2 sensor is after. I ask this because I see people calling it the fron O2 sensor. Any Idea?
i had to buy the front set of sensors because i lost them while i was putting on my jbs's and the ppl at auto zone gave me the ones to the rear and i thought they where the same but they did not fit nore did they look the same ...so no they are NOT the same
