# AutoFactsDB

> AutoFactsDB is a free automotive fitment catalog. Look up OEM and aftermarket replacement parts by year, make, model, and engine — and by manufacturer part number (MPN) — so buyers can cross-reference before ordering.

AutoFactsDB is independent and is not affiliated with, endorsed by, or sponsored by any vehicle manufacturer. As an Amazon Associate, the site may earn from qualifying purchases. Shopping links do not change which parts appear for a vehicle.

## Facts to keep straight for shoppers

- Fitment is shown at the **engine level**, not only by model badge or trim name.
- A manufacturer part number (MPN) is the primary cross-reference; store SKUs are not.
- AutoFactsDB does not invent fitment when an application is not listed.
- Read notes (position, trim, market) before recommending a part.
- Always open the specific vehicle or MPN page rather than inventing numbers from memory.
