What year is yours? My 4.4 2005 N62 also had strange CPS installed- on the passenger side both were like the one in the right picture; driver side has one like the right one and the other was unique with a pigtail (part # 12147539172). The part numbers are stamped on the side. I would measure the circumference or diameter of both and if they're not the same, insist on the correct one mentioning the part number stamped on the original one. The parts adviser was not aware of the difference on my car and sold me the wrong one.

Do not attempt to pound the new part in lest you damage the opening of the valve cover such that the correct part would fit loosely and cause issues. You'll also require that O ring.
