What are the differences between OEM and original parts?
3 Answers
Automotive parts have differences between OEM and original in terms of packaging, definition, and concept. Here are the detailed explanations: Packaging: OEM refers to products manufactured by the original equipment manufacturer (meaning this manufacturer is the designated producer of the product). Original parts are not necessarily OEM products; from a packaging perspective, it simply means the product has not been opened or used after leaving the factory. Definition: When a part fails, OEM parts are the best replacement option, excluding scenarios where large components are upgraded with better alternatives. Concept: OEM parts are components produced by the manufacturer of the equipment itself. These parts are tested upon leaving the factory, but they may not always function perfectly within the entire system.
I've been dealing with auto repair shops for decades. While 'genuine parts' and 'original equipment' sound similar, there's a significant difference. Genuine parts are components produced by the automaker's own factories, like Toyota parts for Toyota vehicles - these are called genuine parts. Original equipment refers to the parts installed when the car rolls off the production line, meaning the factory-installed condition. Using genuine parts during repairs doesn't count as original equipment since they weren't part of the original vehicle. Choosing genuine parts for repairs is reliable as they maintain performance close to original equipment, though they cost more. When buying used cars, people often ask about original equipment - completely original parts mean lower maintenance costs and avoid potential accident risks. Don't cheap out with counterfeit parts - they tend to fail at critical moments.
When I first bought a car, I was also confused. The manufacturer said that original parts are directly produced by the automotive company, ensuring high authenticity. Original equipment refers to the components installed on the car when it was first delivered, such as the tires in the first year of a new car. After they break down and are replaced with new parts, even if they are original manufacturer parts, they are no longer called original equipment because they were installed manually. When I repair the air conditioning and replace the filter, I always choose original manufacturer parts for better compatibility. For minor components, aftermarket parts can save some money, but for the engine, original manufacturer parts are a must—otherwise, fuel consumption may increase or problems may arise. I recommend that beginners do more research and clearly note the source of parts in maintenance records to avoid being scammed.
