Then you run into minimum quantity orders.
Even then the quality will not be up to Bosch levels. For example, the Myna Diesel 7mm elements are available for purchase on their own, and they reportedly don't have the same consistency in injection delivery (idle is rougher, etc).

Bosch arnt doing anything to spectacular. They use the same lathes and grinders that can be found at any machine shop that's properly tooled up.
Bosch quality? Have you SEEN what they're India nozzles look like?
tolerances can be held to a millionth pretty easily these days. Someones gotta know a friend in the trade, usually you can abuse the machines "after hours" (or atleast, I did)
When we used to order Danley die punches, they were $15/each. Each were ground to a the ten thousandth. All were hardened to 65hrc (if I remember correctly) before grinding.
High speed machining is cheap.
