Yes. Every ignition part on this page is engine-specific. Each row shows which engine(s) it fits — use the filter at the top to hide the rest. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.
What are the signs of ignition problems on a 2018 Genesis G90?
Common symptoms include misfires under load, rough idle, flashing check-engine light, or poor starting in damp weather. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.

Notes on this page include pre-set gaps of 0.033", 0.040" and 0.044". Still verify against spec — even “pre-gapped” plugs should be checked before they go in.

What do the market flags (US, CA, MX) on each part mean?

How do I make sure a part fits my 2018 Genesis G90?
