Any auto parts store has them many have them to loan.

AND some NON-SILICONE anti-seize compound.

 

Great! Thanks

 

The sensors are 7/8 inch , crack them loose while the pipe is attached , more leverage, or remove them on the floor after

 

Thanks for the tip!

 

When I replaced my exhaust pipe the leads on the sensors were way to short to reach the ground. I suppose you could unplug them but I went to Harbor Freight and bought a set of O2 sensor sockets for around $15.00;

Mine go on a 3/8ths inch ratchet but an open end wrench will work as well as the sockets. I have been replacing all my tools, mostly at Harbor Freight. My dad was a master mechanic at a few different Ford garages while I was growing up and when he died I got his tools.

I used them for years when I had my own shop.

I am sure if he could come back for just one day he would spend most if it kicking my ass up and down the street for what I did to his tools.

 

I bought the HF 3/8 Drive 7/8 sensor socket but it wouldn’t fit in there with the ratchet.
I disconnected both sensors, I can get to them from up top with the stock air box removed.
My exhaust manifold flange nuts are 9/16, it might be from heat cycles but a 15 mm 6 point was loose on them.
PB blaster helped .
I always drive about 10 miles to warm up those nuts , I can also crack them loose from up top after removing the air box
