Help Replace O2 Sensor

I've determined my O2 sensor is on its last leg and needs to be replaced. I bought the new one and all, but how and god's name do I get the old one out? I know I am trying to unscrew the right thing, but the workspace is just to damn small. And 22mm wrenches dont come small either so that is screwing me up. If you'll could throw some hints or advice on how you did it, it would be much appreciated. And the car is a 1990 LX Sedan, running a stock D15etc. etc. motor. Thanks.

Take off the A/C fan, take off the header heat sheild, and buy yourself an O2 sensor wrench which is a special wrench that will take off the O2 sensor using a 3/8 socket wrench and extension.

Is there anywhere in particular that I would be able to find an O2 wrench, such as an AutoZone or such?

Alright, another florida guy. Just get one from autozone.

If you need any stock honda parts, stop by the Holler Honda Service Center. Soon we will be carrying performance soon, like Spoon, Greddy and AEM.

Thanks turbo, I was thinking of going out to a holler sometime at the end of the month so other various body parts that need fixing. Thanks for the heads-up on the performance parts :dogpile:

Might as well put on a ceramic header while you're at it. It's not much more difficult.
I rented the O2 socket from Autozone for $15.
