ID:	6503Hi .. I have had my 1997 Caddy van mk2 for 7 years . I have just removed the clapped out diesel sdi engine and replaced it with a Golf mk3 petrol 8v and loom.
I have these plugs with seemingly nowhere to go. Can anyone cast al ight on what any of them may be? wondering if some are redundant as maybe for the old sdi engine. Thanks H
