Great help, good videos, thanks so much.....

I do not see how they got the wrench on that way unless the engine was pulled out on the video. Maybe a long 22mm socket will work because it is a tight fit. I tried a 7/8 inch wrench but it would not go on so maybe it has to 22mm. The 7/8 wrench worked on the front O2 sensor where there was also enough room for the wrench, which was supposed to be a 22 mm.

But on the knock sensor, it did not fit like the 7/8 was a little too small. I almost forgot all the details but it does not seem a wrench will fit very good due to the space, so maybe it would need to have a short handle.
