Air-shroud vs non again (sorry)...2 ?'s

[ewanhopkins@hotmail.com (Ewan Hopkins)]

The air-shroud setup I have (ex. 1990 audi 2.0L) has injectors which do not 
look standard but are in fact the same, except that they have small metal 
caps on the ends, which are just push-fit. I took the ones off the audi 
injectors which came with the engine and put them on my original VW 
injectors. Dunno if you can buy the caps separately though.

HTH,

Ewan Hopkins
