My 03 tiburon GT show me check engine light, so i went to auto zone to get an advice, then they said i need to replace O2 sensors.

they said i need to replace all O2 sensors.

next day i went to hyundai dealer to get an estimation, they said i will be around 300 dollars.(bullcrap)

I am trying to replace O2sensors by myself, and can anyone post picture of exact locations of all O2 sensors please?

P.S i have cold air intake and my MAF sensor constantly causes check engine light too(maybe the water went in the intake pipe?). is there any solution to prevent MAF to broke?
