ebay headers O2 ports

[dougsic]

What did you guys with these headers do about the O2 ports?

Did you just crank down on the plug they give you? Crush washer, JB Weld or nothing?

The bung is pretty deep. Do you think it matters that the plug isn't?

that should be fine and is exactly how I plugged my OBDII manifolds. You can always get a longer bolt if you're concerned about exhaust flow

I would use a copper crush washer on it.

How do the ebay headers fit in the E30?

Do they line up with the OBDII dowpipes the same?
