Car owners often face the decision of choosing between OEM and aftermarket parts when their vehicle requires maintenance or repairs. Ultimately, the decision comes down to the budget and specific vehicle needs.
In this article, we will discuss the differences between OEM and aftermarket parts, weighing their pros and cons, and talk about the situations where these options are ideal so that you can make informed decisions to determine the best fit for your car.
OEM vs Aftermarket Parts: Definition
What Does OEM Parts Mean?
Original Equipment Manufacturer (OEM) parts are produced by the same company that manufactured your vehicle. Some retailers also refer to them as “genuine” or “authentic” parts, since they are designed to fit properly within your specific vehicle model during replacement.
What Does Aftermarket Parts Mean?
Aftermarket parts are produced by third-party manufacturers rather than the original vehicle manufacturer. While they can be alternatives to OEM parts, some aftermarket options may be incompatible with your vehicle, as the design varies from manufacturer to manufacturer.
A common misconception is that all aftermarket parts are worse than OEM parts. The quality of aftermarket parts can vary significantly depending on the materials, manufacturing processes, and quality assurance measures. Thus, some aftermarket parts can perform just as well as OEM parts.
OEM vs Aftermarket Parts: Comparison at a Glance
OEM and aftermarket parts are suitable for different situations, as they both have their benefits and drawbacks. You can refer to the table below for a quick comparison and we will delve deeper into their pros and cons in the next section.
| Part Type | OEM | Aftermarket |
| Compatibility | Guaranteed fit | Varies |
| Availability | Usually have limited availability, especially for older models | More readily available |
| Options | Fewer options but consistent quality | Wider range of options with varying quality |
| Cost | Usually higher | Usually lower |
| Warranty | Often backed by manufacturer’s warranty | Limited or no warranty, depending on the manufacturer’s terms |
OEM Parts: Pros and Cons
In this section, we will elaborate on the pros and cons of OEM parts, according to the points listed in the table.
Benefits of OEM Parts
As mentioned, OEM parts are designed to fit perfectly with your vehicle model. This ensures optimal compatibility and functionality, reducing the risk of misalignments that could lead to unexpected performance issues.
Moreover, the production processes of OEM parts are also standardized with rigorous control measures. Hence, you can expect consistent quality and reliability when using them for replacements.
Additionally, OEM parts often come with a warranty. Even though the warranty coverage can vary depending on the manufacturer and specific part, it typically covers defects and malfunctions over a reasonable timespan or mileage.
Drawback of OEM Parts
Due to the brand recognition and stringent quality control measures involved during production, OEM parts are usually more expensive than their aftermarket alternatives. For example, some body parts with complex designs could be priced up to 50% higher.
Also, the availability of OEM parts can be limited because of their high demand. This may lead to longer wait times for restocks and repairs, especially for less common vehicle models. Sometimes, OEM parts for older vehicle models could even be discontinued, limiting your options further.
Aftermarket Parts: Pros and Cons
Based on the table provided earlier, this section will further discuss the pros and cons of aftermarket parts to help you understand this option.
Benefits of Aftermarket Parts
One of the primary advantages of aftermarket parts is their greater availability, as they can be found in various retailers, including auto parts stores, online marketplaces, and independent mechanics. This makes it easier to find the specific part you need, regardless of your vehicle’s age or model.
Furthermore, aftermarket parts offer a wider range of options. Different manufacturers produce parts with varying quality levels and performance characteristics, allowing you to select the best option based on your budget and preferences, whether you’re looking for a basic replacement part or a high-performance upgrade.
The widespread availability and diverse selection further make aftermarket parts more affordable. While the price difference can vary depending on the specific part and manufacturer, the cost savings can be especially significant for larger or more expensive parts.
Drawback of Aftermarket Parts
Aftermarket parts can be inconsistent in quality as various companies manufacture them. Even if they don’t bring safety hazards or poor functionality, they may wear down prematurely and require more frequent maintenance.
On top of that, many aftermarket parts come with minimal or no warranty, leaving you responsible for any defects or failures. You may have to pay out of pocket even if these parts don’t fit well or break down early, so you must be careful when choosing between aftermarket brands.
OEM vs Aftermarket Parts: Which Should You Choose?
Now that you know the benefits and drawbacks of OEM and aftermarket parts, let’s discuss the situations where these options are suitable.
When to Choose OEM Parts
OEM parts are particularly ideal in several situations, including:
When the Vehicle is Still Under Warranty:
Dealerships and manufacturers are more likely to honor warranties when repairs are made with OEM parts. While some aftermarket parts might not void the warranty outright, they can lead to potential coverage disputes or warranty voids if they malfunction.
When Insurance Coverage is Required for Collision Repairs:
Collision repairs often require OEM parts, especially if the repair costs are covered by insurance. Some insurance providers include this term due to the quality assurance of OEM parts.
As OEM parts fit better and meet the original safety standards of the manufacturer, they are also crucial for maintaining the structural integrity of crumple zones after a crash and help you return your vehicle to its pre-accident condition.
When Aftermarket Choices Feel Overwhelming:
Aftermarket parts come in various brands and quality levels, which may confuse those unfamiliar with the market. In such cases, OEM parts can be a straightforward and reliable option.
While OEM parts cost more upfront, the investment can be justified as they guarantee fit and function while offering a manufacturer-backed warranty. In turn, you can avoid purchasing inferior or incompatible components.
When to Choose Aftermarket Parts
Here’s when opting for aftermarket parts is more ideal:
When There are Budget Constraints:
Repairs and maintenance can sometimes be expensive but avoiding necessary part replacements could lead to more severe issues later. With aftermarket parts, you can have your vehicle fixed at a cost-effective rate and stay within a tight budget.
When Quick Repairs are Needed:
If you’re hurrying to get your vehicle back on the road, aftermarket parts may be more suitable since they are often more readily available than OEM options. Many auto shops stock a wide range of aftermarket parts, reducing potential delays due to ordering or shipping times.
When the Vehicle is Older:
As vehicles age, the lower cost of aftermarket parts makes them a more practical choice. Older vehicles are usually more prone to wear and require more frequent maintenance, so the expense of OEM components may not be worth it.
Additional Considerations
Remember that you should always research the manufacturer when selecting aftermarket parts. A trusted brand can help you balance quality and affordability, ensuring these parts perform well and last longer. It is also best to look for aftermarket parts with warranties to add protection against defects.
