For the archives: O2 non-fouler mod does NOT work with Zoldman O2 sensors.

i bought the non-foulers (#42009) and i bought a 1/2" drill bit and a 5/8" drill bit. Using the 1/2", the opening is not large enough to fit the O2 sensor. Using the 5/8", the walls of the fouler became so thin that they were breaking and you could see through them. Im assuming my problems are because my O2 sensors are not stock? I dont know, but i'm a little disappointed, i really wanted to kill that CEL. later guys

i was under the impression that the spark plug non-foulers will only work with stock O2s

It has been confimed by others that the 5/8 is too big. BTW the stock sensors and the VAST ones....

are dimensionally identical. 15mm at the portion of the tip beyond the threads.

Nick Gustas got it right. see his thread below:<ul><li><a href="https://forums.audiworld.com/s4/msgs/2239514.phtml">https://forums.audiworld.com/s4/msgs/2239514.phtml</a</li></ul>
