Hi,

No, it's not a Jag cap, this is the proper cap for marelli - porsche twin plug dizzy.

It might be a repop, as these ones have been redone by at least 2 different producers. Check eleven parts site to compare.

You can buy them new for about 150$ - 200$ each (cap and finger)

Where does it come from?

For me, they look right! And might be worth using them on a twin pluged engine!

If they are original NOS, they are worth an arm plus a kiddney, and maybe a nut...

Olivier.
