The Supertech intake valve for Honda RSX K20 applications is a black-nitrided 37.5×5.48×109mm dish-style intake valve offered as a single item. Intended for intake-side service or targeted replacement during a rebuild, this valve matches factory dimensions and provides a direct-fit option when only one valve needs replacement rather than a full set.
