Under Air induction on the G-2 section it doesn't state anything about spacers, even an aftermarket intake manifold doesn't require an E.O. Yet some spacers have an E.O. and some don't.
Note: Any add-on or modified part not otherwise addressed in this table must have an EO and be verified during inspection.
^^That's at the very end of Appendix G. At the bottom of the table that lists which parts need EOs.
