Original-equipment (OE) reference numbers are the codes the vehicle builder prints on the part it fitted at the factory. This hub indexes those numbers by part category so you can cross-check what came off your car and see every compatible aftermarket replacement. Pick a category below to browse OE numbers and jump to brand-specific alternatives from Bosch, TRW, Brembo, SACHS and dozens of other tier-one suppliers. Every listing ties back to fitment data, so an OE number you find here maps cleanly to parts that actually fit your chassis.
