Does anyone know what size wrench I need to remove the O2 sensors when removing the cats from the car? Any help would be greatly appreciated.

22 mm I believe.

 

Thank you.

 

it's actually a 7/8. we recommend buying a socket specifically made to remove o2 sensor's. you can buy them from sears. we use only snap-on tools here, which are the best you can buy. for your purposes, however, sears will be just fine. hope this helps.

 

That worked, finally put them on this weekend. I tell you what, it sure is a sweet sound with the Borla headers, Injen CAI, XERD Test Pipes and the full Borla cat back exhaust system.
