i was wondering if you could buy an o2 sensor wrench at the subaru dealership? if not where is the best place to do that?

thanks

 

Any auto parts store or even Sears has them.

Get the one with the larger opening for the wire on the sidewall of the socket. Some only have a little slit but for the UP and DP install in subies you need that wider hole to have some clearance to work it in there.

 

i thought they only came in 1 size?

 

darn, i wished i would have asked that question when i did my uppipe. my sensor was seized up and i ended up just removing the stock up pipe and the sensor itself. i just capped it off.

i hate to ask, but are you trying to reuse your egt sensor?

 

You can rent O2 sensors at Autozone. When I did my UP install, we rented a set at Autozone. They had 3 different sizes, and one of them worked fine for it. It was $15 IIRC. Returned it the next day and got my money back.
