The factory cup becomes loose over time causing fuel and coolant cross-contamination.  The new billet injector cups are also engineered with dual silicone o-rings that are each 2x the size of the single factory o-ring seal.  This feature also allows the cylinder head to expand and contract, keeping the seal between the cylinder head and injector cup Intact.
