Mein Auto: Z3 3.0i Roadster, K1300S
We had a spark plug discussion in another thread that included the issue of the $20 "BMW" Bosch platinum spark plugs vs. the $6 Bosch platinum spark plugs (e.g., Advance Auto Parts). Ron Stygar posted that Bosch told him that the two plugs are identical.

When I changed the original NGK spark plugs in my 2001 Z3 3.0 a few months ago at about 75,000 miles, I went with the $20 spark plugs from the dealer (which were Bosch). The original plugs looked fine and the car ran fine, but it just seemed time to change plugs. With the new plugs installed, the car started up and ran smoothly immediately, and has run fine ever since.

Here is the other thread. Your choice.
