IIRC I got some Bosch seal kits in the past that I didn't like (or use) because of some differences in the pintle cap, and the little spacer was significantly different as well.

 

Bosch changed the pintle caps and no longer offer the original type. Do a search as there are a lot of threads on this topic. My car had the newer caps and I had no problems but now I'm using siemens. I thing rennbay found a universal set that fits quite well.
