Customer Q&A
Ask a question to 1A Auto customers who purchased the product
What size socket is needed for removal of downstream O2 sensor?
Chris O January 14, 2016
7/8 socket
Gilbert B January 19, 2016
Got this over a year ago unfortunately it never made it on the car because it got in an accident. 1A Auto even credited the item back to me. If my memory serves me right I found a video on Youtube that explained everything including what size socket to use
NICHOLAS C January 19, 2016
O2 sensors take a 7/8 or 22mm wrench or 02 sensor socket.
T E September 5, 2017
22mm = 7/8 Make sure you use a proper socket because the wiring will be weird
