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 Chevrolet Malibu?

Notes on this page include pre-set gaps of 0.026", 0.028", 0.030" and 0.054". 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?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2018 Chevrolet Malibu was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2018 Chevrolet Malibu?
First match the engine — each row shows which engine(s) the part fits. Then gap matters even on “pre-gapped” plugs — verify against spec, and replace coil boots when they come off a high-mileage engine. The notes column carries position and trim qualifiers where they apply.
