Genuine, OEM, Aftermarket or Used Car Parts: What's the Difference?
Genuine, OEM, aftermarket and used parts explained in plain language — how they differ, when each makes sense, and how to make sure you get the right part.
By Lionized Autocare ·
When a part on your car needs replacing, you’ll usually be offered more than one option — and the labels can be confusing. Here’s what they mean, and how to choose.
Genuine parts
Genuine parts are supplied through the vehicle manufacturer’s own parts channel, usually in manufacturer-branded packaging. They are designed for your vehicle and typically match the original part exactly.
Best for: safety-critical and complex components, vehicles still under warranty, and situations where an exact match matters. Consider: they are often the most expensive option, and availability depends on the vehicle and part.
OEM parts
OEM stands for original equipment manufacturer — the company that made the part fitted to your car at the factory. An OEM part may be essentially the same as the genuine part, but sold under the maker’s own brand rather than the vehicle manufacturer’s.
The terms “genuine” and “OEM” are often used loosely, so it’s worth asking exactly what is being offered.
Aftermarket parts
Aftermarket parts are made by other manufacturers to fit your vehicle. Quality varies widely: some are excellent, others less so.
Best for: common wear items and cost-sensitive repairs, where a reputable aftermarket brand performs well. Consider: fit and finish can vary; ask about the brand and its reputation.
Used parts
Used (second-hand) parts are removed from another vehicle. They can be a practical way to find a component that is expensive new or hard to find — particularly body panels, trim, lights or some mechanical assemblies.
Consider: condition varies from one part to another, so used parts are best for components where condition can be checked, and less suitable for safety-critical wear items such as brake pads.
Getting the right part — whatever you choose
Many vehicles in Kenya were built for other markets, and parts can differ between versions of what looks like the same model. To get the correct part first time, have these ready:
- Make, model and year
- Registration number
- VIN or chassis number (on your logbook)
- The part number, if it’s printed on the old part
- Photos of the part and where it fits
