Why parts lookups start with the VIN
Parts retailers like O'Reilly use the VIN because it pins down the precise engine and configuration that determine fitment — the same model year can have multiple engines, and the wrong one means the wrong part. Decoding the VIN gives you the year, make, model and (critically) the engine code from position 8, which is the information a parts counter or online catalog needs.
Our decoder reads all of that from the VIN for free and validates the check digit so you don't transpose a character. Take the decoded year/make/model/engine to any parts catalog for an exact match.
Decode for fitment, then verify the vehicle
If you're buying the car (not just parts for one you own), the same VIN can be run through a full history report to check title brands, accidents and odometer — useful before you invest in repairs.

Which VIN character is the engine code for parts?
On most vehicles, position 8 (the last character of the descriptor section) is the engine code. Combine it with position 10 (model year) for an exact match.
