Bazzaz O2 Sensor Bung 4 5 3 3
Best Website Ever!!! This bung was perfect, toke to a guy to weld it he loved it, he said the edges and workmanship of the bung were spot on. Once it was welding on it didn't warp or anything from welding. To this day I haven't had a single issue with it. June 14, 2016
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
