bung

as topic says! is it smart of my adding a wideband o2 and EGT bung, in case of later performance tuning ? What is the EGT ? If yes, Where should they be placed ?

I want to fit a EGT Gauge, but the bung on the top of my d/pipe looks to be a 18mm Lambda :( So what i need to know is it possible to get an adapter of some sorts to convert 18mm to 1/8npt, i have found this but it looks like its made of brass so probably no good...

ok, speaking to Jenk, and he has prefacelift wings, but with an aerial on the roof... this means a redundant hole in the wing, which was filled in with a bung... is this bung available from seat...? it must be a seat part but phoned SEAT barnsley and the guy had no idea... but to be fair, he had...

Since ive fitted my guages i had to cut a hole in my bung behind the wiper motor. Problem is I cant fit it back into the hole now and this morning a bit of water spilled down onto my feet. Anybody bodged this or is there another way like gluing it down or siliconing it?
