Fits perfectly
Just what I needed to convert my schwaben 2 tab for bmw to 4 tabs VW EA888B 3rd gen.

If you have a 4 prong cap this is the adapter you need.
Works perfectly, if you have a 4 prong cap this is the adapter you need. Also applies for the Audi lineup as well. The factory fill hole is difficult to stabilize a filter into, this adapter is worth it even for the home mechanic to make the job easier.

Great add on
Have not been able to use it but from what I can tell it will seal great and fits my funnel I bought previously.
