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 1990 Lotus Elan 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 1990 Lotus Elan?
Every part on this page is matched to the 1.6L L4 Turbocharged engine.
