Hey guys, I have a quick question. Are the oxygen sensors in a 2000 ex the same as a 2000 si? I'm buying from a guy on here and he has the front sensor for an si and he only has rears in stock for an ex. He says they are the same he thinks but I just want to double check. Thanks a lot!

 

The front O2 sensor for the EX and Si are different. The rear O2 sensor appears to be the same.

You can check it out at oxygensensors.com.

 

cool, thanks man
