it does seem a bit off.....as far as mileage i normally get about 3000 mi from a cap.
actually it looks better than mine usually do.
like blas said the center electrode is usually the pain you get from these caps. just bend the rotor tang up to be assured of a good contact. i found caps to be a bit sloppy of a fit on the housing.

msd told me to drill a small hole in mine, oriented to the rear of the cap
