Skunk2 Racing’s VTEC block-off plate replaces the factory spool valve assembly on K20 and K24 K‑Series engines when VTEC is no longer active. CNC-machined with a black anodized finish, it uses the OEM O‑ring and provides a clean engine-bay appearance for VTEC‑deleted setups. The solid block-off simplifies the intake area while maintaining a direct, bolt‑on replacement for the stock spool valve.
