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 1991 Saab 9000?
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 0.035", 0.039", 0.040", 0.044" and 0.045". 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 1991 Saab 9000 was originally sold in the US, the safest choice is a part marked for the US market.
