The Billet Torque Lock Injector Cups are designed to thread into the cylinder head creating a locking bond between the cup and the cylinder head. They are designed to fix the issue of the factory Injector cup that is press-fit into the cylinder head. 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.
