I've not used them yet but as they're dated 1996 (it also says 97 MODEL Year on some pages) I assumed they're as stated on the file name as a 300TDi so would be good for my 1994 300TDi. I believe it's replacement the TD5 didn't come in till 1998.
I'll stand corrected as I'm far from expert and would love to have this confirmed (hive mind?)
