How to tell if a replacement part is fake or generic

Sellers pass off unbranded parts as legitimate, shipping them in generic boxes without proper brand markings. Installing these suspected counterfeits can cause severe performance issues like engine misfires, leaving buyers relying on minor visual defects like faded or running ink to catch the scam.

“I recently purchased a wheel hub for a 1996 Camaro on eBay, thinking it was NOS Moog. (Yes, I know Moog isn’t what they used to be) The seller is trying to claim the top wheel hub is Moog and was made before they marked their products. The item was shipped in the typical Chinesium box.”source ↗
