Hi everyone.

I am currently resto-ing my S2

Part number Bosch 0 580 254 910

And I have a saff cossie one from a friend

Part number Bosch 0 580 254 941
the cossie one is smaller that the one that was on my S2.... does any1 no which would be best to use.

engine spec will be 1.9cvh+stg3 head, efi with cossie managment and green injectors if thats any help.
Thanks in advance!
