only thing Ive heard about the bosch's is that the extra tips on them can break off. Actually had that happen to a friend, no engine damage but Im sure you can imagine what that could do to an engine...

I had the same issue with the Bosch 4 plat. I took those f-ers out and put brand new motorcraft ones in and everyhting was perfect. They might be great plugs but not on the 4.6 stangs.
