just like the title states. my o2 sensor decided to go out and its the hardest one in the vehicle, you know the only located at at the firewall. no socket can fit correctly in the small space available. i have tried the o2 socket wrench and a regular wrench. i just get enough leverage to make anything happen. instead i went ahead and started to look into remove the Y pipe in hopes to remove the o2 sensor that way. well it seems that my bolts are some strange size. i dont own a metric or standard wrench that fits the strange bolt size. in the video below i used a 14mm wrench to show that it doesnt fit and neither does a 13mm or a standard sized wrench. what should i do?

Buy a metric set of spanners and sockets . A must for DIY
