Questions
Genuine, OEM or aftermarket — which car part should I buy?
Genuine (from the manufacturer) and OEM-equivalent parts match the original spec and are safest for critical components; quality aftermarket parts can be good value for non-critical items; used parts save money but need careful inspection. Match the choice to the part.
How do I avoid counterfeit car parts?
Buy from reputable sellers, check the part number and packaging, be wary of prices that look too good, and confirm a return or warranty policy. Counterfeits are common for fast-moving parts like filters, brake pads and electricals.
