HELP. WHAT SPECIFIC SPARK PLUG NON FOULER WILL THREAD IN o2 BUNG

[MrDniceL36]

For 1998 Grand Prix GT 3800
What Specific Non fouler fits and threads into my downstream o2 bung????? I just scanned a po141 code. 78 MILES AFTER INSTALLING NEW ZZP MAGNAFLOW HI FLO CATTED DOWNPIPE... So im going to replace both sensors and do the non fouler trick with 2 non foulers and then hope it cures my CEL. ???
Any more help is appreciated!

Look at this on eBay:

O2 Oxygen extension universal HYDROGEN spacer HHO gas M18 X 1.5 18mm size thread
One of these will do you fine. After making my own and having it break I just bought this one. No issues for 6+ months
