Found these on ebay for a set of 4 or other sellers have them individually,Standard Intermotor injector # FJ6-4 listed for a few other VW's also,411/412 and FI Beetle for example.
Seems to be listed by several vendors but some only list #FJ6 for the same application so don't really why there is 2 part numbers ?.
Would be interested on opinions from those that have used them,need to know before buying TIA.
