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 2021 Mitsubishi Outlander was originally sold in the US, the safest choice is a part marked for the US market.
