The machining on this bung is horrible.
I ordered 2 of these bungs. The machining was a little better on one of them, but still very poor. I couldn't thread an O2 sensor into either of them, I had to buy a $60 tap to run through both of them. These are way overpriced, especially for the poor quality machining.
What's a guy to do though? I still used them, but basically had to re-machine the threads.

Affordable price and does its job
Good price and quick shipping! Works well in keeping the O2 sensor secure.

Chris L: Needed to mount 18mm bung with Z-AFM. A shame that you cannot reuse the OEM O2 sensor (12mm) because now a separate bung is required. Yoshi R-77 mid pipe came with pre-mounted 12mm. This bung does NOT come with the plug.Dec 31, 2014
Frank C: Simple enough, I needed it to install the O2 sensor for the Bazzaz Z-AFM. Works great.Oct 13, 2013
