Genuine vs OEM vs Aftermarket

One part number is sold at three quality tiers. Know what you are comparing before you compare price.

Genuine
Genuine (dealer)

Sold in the automaker's own box — BMW Genuine, Toyota Genuine. Identical to factory-fit and the safest match, at a premium.

OEM / OES
OEM / OES

Built by the same supplier that makes the factory part — Bosch, Mahle, ZF — and sold under their own label. Factory quality, better value.

Aftermarket
Aftermarket (AFM)

Made by third parties to fit the same application. The widest price range, and quality varies by brand — check the seller rating.
