5 Benefits of Buying OEM versus Aftermarket Parts – Trust in Authenticity

OEM vs Aftermarket Parts

Repairs and routine maintenance are essential parts of owning and operating a vehicle. Because of this, you should seek out qualified mechanics who can deliver top-notch service and guarantee the safety and stability of your car. Otherwise, you risk having it suffer damage that might be costly.

Providing the best kind of parts necessary to replace broken or worn-out components is an important aspect of high-quality service. With that in mind, it’s always best to opt for car technicians who only use original equipment manufacturer (OEM) parts.

Indeed, there are countless cheaper options available in the market. These are referred to as aftermarket parts, which the original equipment manufacturer doesn’t make.

While inexpensive, these may negatively affect your vehicle’s performance or cause unexpected issues, costing you more money.

But unlike aftermarket parts, OEM parts are designed by vehicle manufacturers and are identical to the parts that need to be replaced. Although they tend to be more expensive, it has more benefits than aftermarket items. If you decide to buy an OEM part, look for trustworthy providers online or find it here.

If you’re still not convinced about buying OEM parts, here are some of the benefits you can enjoy once you do so:

1. Guaranteed Quality

Nothing’s worse than spending money on aftermarket parts that aren’t compatible with your vehicle and could eventually cause damage. With OEM parts, you can be sure that they will fit your vehicle perfectly and perform as intended. Due to their high quality, their price is justified.

2. Manufacturer’s Warranty

Just as you’d want to get extended warranties for your car, you should also get coverage for its parts. Unfortunately, this is something that sellers of aftermarket parts can’t offer. The good news is that when you buy OEM parts, you can be sure to have additional financial security through a warranty.

Most original equipment manufacturers take customer service seriously to protect their clients from losses and defects in the parts purchased from their company.

Furthermore, some manufacturers even offer a free replacement when their OEM parts don’t meet performance standards or are faulty. With such warranties, vehicle owners can save money while keeping their vehicles in optimum condition.

3. Durability

One of the primary benefits of buying OEM versus aftermarket parts is durability. When compared to OEM parts, aftermarket products don’t provide the assurance that comes with getting an item specifically designed to meet your vehicle’s requirements.

Typically, the specs of aftermarket parts are less precise since their features are modified for budget purposes. Moreover, they don’t meet the strength and quality required to help your vehicle perform properly. In fact, the forced fit or additional wear may also reduce your vehicle’s fuel efficiency, resulting in poor performance and higher repair costs.

On the contrary, OEM parts have long-term reliability, which guarantees that you get value for your money. Undoubtedly, such investments will offer you the financial protection that you require.

4. Longevity

Even if you can enjoy savings with aftermarket parts, there’s a possibility that they might put more strain on your vehicle, which will require you to have them replaced immediately. They can also break sooner than you anticipate. So, purchasing OEM parts could be cheaper over time as they last longer.

OEM products may also lengthen the lifespan of your vehicle’s components. As a result, you won’t worry about replacing them periodically.

5. Better Efficiency And Performance

OEM parts are rigorously tested and smartly designed to match the car manufacturer’s strict standards. Original equipment manufacturers must meet particular industry standards throughout the testing and manufacturing process in order to make the automotive components qualified. Thus, you can ensure they won’t negatively affect your vehicle’s efficiency and performance.

Some of the industry standards are Automotive Electronics Council (AEC)-Q100, AEC-Q200, and International Automotive Task Force (IATF) 16949:

AEC-Q100 – It’s the standard test used for active components, including power amplifiers (Pas) and switches.
AEC-Q200 – It covers tests for passive devices, including cellular communications and Wi-Fi.
IATF 16949 – It’s the global standard in the automotive industry that ensures quality management, which means all vehicle parts must be tested, assembled, and manufactured in any qualified facility.

Several of these tests are unique to the automotive industry and not intended for components designed for commercial use. For example, tests conducted under harsher conditions must only be used for commercial parts to ensure the reliability of components.

When repairing your vehicle, finding parts that fit and work properly is crucial. Therefore, you should consider getting OEM parts since they can fulfill your repair requirements.

Although many low-priced aftermarket parts are functional, they may not completely assure that your vehicle will run properly, especially if they’re made of subpar materials. So, never hesitate to buy OEM parts to keep your vehicle in good condition and avoid potential problems.

Go To The Nearest Dealership In Your Area


To keep things simple when buying OEM parts, visit the nearest dealership in your area. Most local dealerships may have the OEM parts you’re looking for or can request your preferred parts from the manufacturer. While it may save you time, you should expect to pay more for the dealership’s service.

Contact The Manufacturer

If you need a particular OEM part and you can’t find it anywhere, your best resort is to contact the manufacturer. Depending on the manufacturer’s customer support options, you can send an email or call its sales representative. Typically, manufacturers have dedicated sales teams who can assist you with your needs.
