O2 sensor bung size

Does anyone know what thread size is on the O2 sensor bung on V&H BSS? Its not a pipe thread. I may be a bolt thread. When installing the PClll you don't need the sensors so I thought I would leave them on the old pipes in case I ever had to put them back on. Wanted something to plug the holes with that will look clean. Any ideas?

Yup, metric. M18 x 1.5. Plugs are readily available, here's some from Eastern Performance Cycles.

YOU CAN BUY THEM AT MOST AUTO PARTS STORES AS DRAIN PLUGS... THEY ARE NOT CHROME THOUGH...

Like Josh said... i got mine at Advance Auto Parts for like $3 a piece. They're not chrome though so they'll tarnish when you put some major heat on them. But then again...do you really care and who looks at them there anyways? The one nice thing about buying them at the auto parts store is that its not an internal hex like the plugs in the J&P catalog. It's an external (i.e. male) hex that is big and beefy and if you ever really needed to put some torque on it you could without stripping it out.
