Start with the application branch
Record the engine code, turbo or naturally aspirated branch, plug reference, thread diameter and reach, seat form, terminal style and requested set quantity.
Do not gap or substitute precious-metal plugs from a generic application table. An incorrect reach or heat range can damage the engine even when the thread starts normally.
Identification checkpoints before price comparison
For spark plug sets, record 2.0l or 1.5t engine branch, verify thread, reach and seat form, and photograph heat range and electrode design on both the installed and removed component.
Scoped OE reference
| Reference | Catalogue scope used for identification |
|---|---|
| 12290-5A2-A02 | Selected 2022 Civic 2.0L LX/Sport sedan and hatchback applications; four required per engine in the reviewed catalogue. |
| 12290-6A0-A01 | Selected 2022 Civic 1.5T EX/Si/Touring and higher hatchback applications; verify exact trim and calibration. |
Reference 12290-5A2-A02 is retained only as a spark plug sets identification lead; the submitted vehicle, installed component and any later supersession must remain within its stated catalogue boundary.
Common order boundaries
Build a comparable B2B order line
Keep 2.0L and 1.5T plug references on separate lines and state whether quantity means individual plugs, engine sets or master-carton packs.
Quote four-plug engine set separately from single diagnostic replacement, documenting trial and repeat quantity, destination, Incoterm, label requirements and included hardware for that SKU.
Export packing checkpoint
Use divided cells to protect ceramic insulators and electrode gaps, keep terminals dry and prevent loose metal hardware from contacting the firing ends.
Common buyer questions
Which Civic details separate spark plug sets variants?
Record the engine code, turbo or naturally aspirated branch, plug reference, thread diameter and reach, seat form, terminal style and requested set quantity. Record 2.0l or 1.5t engine branch, thread, reach and seat form and heat range and electrode design before comparing candidates.
What should a spark plug set photograph show?
Photograph the complete installed location and removed component, then add clear views of heat range and electrode design, mounting points and every connector, port or seal. Use named endpoints and units for any measurement.
How should the listed OE reference be used for Spark Plug Sets?
For spark plug sets, the displayed reference is a narrow catalogue starting point only. Keep its visible vehicle boundary attached and confirm the installed component plus any later supersession before quotation.
How should four-plug engine set be prepared for export?
Keep 2.0L and 1.5T plug references on separate lines and state whether quantity means individual plugs, engine sets or master-carton packs. Use divided cells to protect ceramic insulators and electrode gaps, keep terminals dry and prevent loose metal hardware from contacting the firing ends. State quantity per SKU, destination, packing and buyer-label requirements separately.
