| Item | Figure | Where it comes from |
|---|---|---|
| 2TR-FE plug | DENSO FK20HR-A8. Gap 0.031 in. (0.8 mm). | Ignition system, spark plug |

The 2TR-FE lists DENSO FK20HR-A8. The 2GR-FKS lists DENSO FK20HBR8. Both gaps are 0.031 in. (0.8 mm).
The notice says the plugs are iridium-tipped and that the gap is not adjusted.
Publication OM04013U does not print a firing order in the ignition system, so this page has no sequence drawing. The shared gap does not make the two DENSO numbers interchangeable.
Outbound links only. BaySheet does not sell parts. Confirm fitment on the retailer page. Amazon links are searches for a real part name plus this vehicle. Tool rows do not get a product search. The search is not a part number.

The maintenance checklist is on the site now. The email list is not sending yet, so this box will not store an address.
Same repair, different model year. Use the page that matches the truck or car in the driveway. A figure on one year is not a figure for the next.
These guides cover the same kind of work. Their numbers belong to those vehicles, not to this one.
