No. FC16HR-Q8 is the 2.5L A25A-FKS. FK20HBR8 is the 3.5L 2GR-FKS. The gap printed once in the table is 0.031 in (0.8 mm), and the notice says not to adjust it.
It is not printed in the ignition block that was read, so no sequence drawing is on this page.
The maintenance checklist is on the site now. The email list is not sending yet, so this box will not store an address.
These guides cover the same kind of work. Their numbers belong to those vehicles, not to this one.
