comments: a 22mm wrench is fine for taking off the OEM o2 sensor, but putting it on seems to be the real problem, the new o2 sensor sits a bit more in the exhaust manifold and you can't put the 22mm wrench onto it, this is why you need a special o2 sensor socket so you can tighten it even though the nut is inside the exhaust manifold
i didn't show a picture of the o2 sensor socket, but i went out and got one just to tighten it up, it cost me about $8 after tax at my local auto parts shop, it's basically a 22mm deep socket with a slit on the side for the wire, it attachs to a 3/8" drive ratchet and makes the job much easier
