Here are some updated pictures:

1) Before and after. What your modified non fouler should look like after you drill them

shameless plug for BMW F1 Motorsport

2) Noticed how the spark plugs sit snuggly into the spark plug defouler. Again, you drill the defouler so that the oxygen sensor plug's tip can fit inside. If not, there is no way for you to screw on the 02 sensor since the hole is just too small.

shameless plug for UUC motorwerks

3) different angles of the oxygen sensor tips installed in a modified non fouler.
