K-series Note:
This is a required component when converting a factory single valve spring equipped K20A2/Z1/Z3 engine to dual valve spring. Dual valve spring retainers and keepers are required as well to complete the conversion. None of the factory single valve spring valve-train components are compatible with a dual valve spring upgrade.
