- Listed MOQs for these spark plugs start at 200 units per SKU. Factories often accept a smaller trial order for first-time buyers at a higher unit price.
- Will these spark plugs fit my 2018 Honda Civic?
- Every part on this page is matched to the 2018 Honda Civic by OEM fitment data. Before ordering, confirm your exact OEM number, trim and drivetrain on the part page — interchange can vary by trim, engine and build region.
- What must match when sourcing replacement spark plugs?
- Match the OE heat range, thread diameter, reach and seat type exactly — the wrong heat range causes fouling or pre-ignition. Iridium and platinum fine-wire center electrodes give long service life and stable ignition; verify the precious-metal tip diameter, that plugs ship pre-gapped to spec, and that the insulator uses high-purity alumina with anti-flashover ribs.
