Advance Auto Ordering Parts: VIN: P or VIN: 3?

I'm ordering parts for a 2000 Ford Focus. I'm trying to determine which option I should select for engine. It has:

2.0L 122CI L4 FI VIN: P

2.0L 1989CC L4 FI VIN: 3

how would I know which one to pick?

Added (1). Would it be the 5th or 8th number of the VIN?

Added (2). its a 2.0L L4 DOHC 16V

First look at your vin number to see if it has a p or a 3. Failing that, call Advance auto and ask them. Often could mean flex fuel or not.

Check the 8th digit of your Vin number, that's the engine code.

Save yourself from buying the wrong parts by getting them from Advance Auto. That way you won't be waiting for a week to return parts and hope you get the correct ones next time!

DUH, P or 3 in your VIN.

Hi well unless you get the right one it will not be the right part.
