Bazzaz O2 Sensor Bung 3.5 5 2 2
Poor machining 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. November 11, 2014
Affordable price and does its job Good price and quick shipping! Works well in keeping the O2 sensor secure. August 26, 2013

RevZilla Store asked: Why did you choose this?
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
Hernan Rene C asked: so far I need is M18 x 1.5mm, this serves me? Apr 27, 2015

Chris L: The Bazzaz O2 sensor bung is threaded in M18x1.5mm.

In terms of that serving you, it would depend on which O2 sensor you are using. If you are using the O2 sensor that came with a Bazzaz Z-AFM, then this will work.

If you are trying to use your bike's stock O2 sensor with a slip-on, this may not work. For example, the Honda CBR1000RR sensor is threaded in M12.
