I think the problem is that the threaded portion is too long and it will
encroach into the cylinder area. Fast German Auto website gave me the info.

I received a set of platinum 4 plugs from the local VW shop when I bought
tune up parts for my '85GL.  Are you saying that I'm not supposed to run
quad plugs in my 1.9L?
