The 1.5 L specifications page lists NGK ILZKAR8H8S for models without SPORT mode and NGK ILZKAR8J8SY for models with SPORT mode.
The 2.0 L specifications page prints NGK DILKAR7H11GS, NGK DILKAR7G11GS, and DENSO DXE22HQR-D11S. It does not print a footnote that assigns those three to a trim.
Neither specifications page prints a gap, a socket, or a coil torque. Maintenance Minder item 4 says replace spark plugs and does not print a mile interval in the chart that was read.
Oil capacities for these engines are on the 2019 oil guide. The 2021 Civic plug page is a different book and is not a source for these numbers.

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.
