Is it OK to use aftermarket car parts?


When it comes to maintaining or repairing your vehicle, one of the most common questions car owners face is whether to use aftermarket car parts or stick with original equipment manufacturer (OEM) parts. At Kevin's Autos, with decades of experience in car maintenance and repair, we understand the importance of making informed decisions about your vehicle. In this article, we’ll explore the pros and cons of aftermarket car parts to help you decide what’s best for your car.


What Are Aftermarket Car Parts?


Aftermarket car parts are components made by companies other than the original manufacturer of your vehicle. These parts are designed to function the same as OEM parts but are often produced at a lower cost. They are widely available and can be used for a variety of repairs, from replacing brake pads to fixing a damaged bumper.


The Pros of Using Aftermarket Car Parts


There are several advantages to choosing aftermarket parts for your vehicle:



  • Cost Savings: Aftermarket parts are typically less expensive than OEM parts, making them a budget-friendly option for repairs.

  • Wide Availability: With numerous manufacturers producing aftermarket parts, you’ll have a broader selection to choose from, often with varying price points and quality levels.

  • Comparable Quality: Many aftermarket parts meet or exceed the quality of OEM parts, especially when sourced from reputable manufacturers.

  • Customization Options: Aftermarket parts often include performance upgrades or aesthetic enhancements that OEM parts may not offer.


The Cons of Using Aftermarket Car Parts


While aftermarket parts have their benefits, there are also some potential drawbacks to consider:



  • Quality Variability: The quality of aftermarket parts can vary significantly between manufacturers. It’s essential to research and choose trusted brands.

  • Warranty Concerns: Some aftermarket parts may not come with a warranty, or their use could potentially void your vehicle’s warranty. Always check your warranty terms before proceeding.

  • Fit and Compatibility: In some cases, aftermarket parts may not fit as perfectly as OEM parts, which could lead to additional adjustments or issues.


When Should You Choose Aftermarket Parts?


Aftermarket parts can be a great choice in the following situations:



  • You’re looking for a cost-effective solution for a repair.

  • You want to upgrade your vehicle’s performance or appearance.

  • The part you need is no longer available from the OEM.

  • You’re working with a trusted mechanic who can recommend high-quality aftermarket options.


When Should You Stick with OEM Parts?


OEM parts might be the better option if:



  • You want to ensure the exact fit and compatibility for your vehicle.

  • Your car is still under warranty, and you want to avoid any potential issues with coverage.

  • You prefer the peace of mind that comes with using parts made by the original manufacturer.


Final Thoughts


Ultimately, the decision to use aftermarket or OEM parts depends on your specific needs, budget, and preferences. At Kevin's Autos, we recommend discussing your options with a trusted mechanic who can guide you toward the best choice for your vehicle. Whether you choose aftermarket or OEM parts, the key is to prioritize quality and reliability to keep your car running smoothly for years to come.


Frequently Asked Questions

Is it better to buy genuine car parts?


Genuine parts are more expensive than other auto parts because they carry the company logo. Keep in mind that genuine parts are not necessarily better than OEM or aftermarket parts. Ace Auto Parts can give you recommendations on which parts to buy based on their quality and performance rather than who made them.



Do mechanics use aftermarket parts?


When you take your car to the dealership's service department for repairs, you know you're getting original equipment manufacturer (OEM) replacement parts. But if you visit an independent mechanic, you're more likely to be offered aftermarket parts — that is, parts not sourced from the automaker.



Is it safe to use aftermarket parts?


Some consumers worry about the quality or safety of aftermarket parts but these fears are unfounded, according to auto experts. Using aftermarket parts can be more cost-effective than using OEM parts.



Will aftermarket parts void car warranty?


Using aftermarket parts is not in most cases justification for voiding a warranty. What is a Warranty? The dictionary definition of warranty is a legally binding promise from a manufacturer or seller that a product is fit for use as shown, free from defects, and in line with specifications and safety requirements.



Do aftermarket parts devalue a car?


Aftermarket Can Affect Resale Value
While these may enhance the performance and appearance of a vehicle, they typically reduce the vehicle's resale value. Most buyers aren't going to be looking for custom wheels. Rather, they're happy with the factory wheels.



What are the disadvantages of aftermarket parts?


Lower Quality
It comes as no surprise that aftermarket parts are made with cheaper, lower-quality materials. Of course, that means they are not as durable. When your aftermarket parts wear out after only a few months of operation, you can flush those cost savings down the drain!



Can dealerships use aftermarket parts?


There is no specific rule requiring a dealer to use OEM parts when working on your vehicle, but some car companies actively discourage the use of aftermarket or salvage parts due to liability and quality concerns, especially regarding structural components.



Are aftermarket parts as good as original?


Aftermarket parts are less expensive, more readily available, and offer a wider range of options. However, the quality of aftermarket parts can be inconsistent. On the other hand, OEM parts offer greater quality assurance and come with warranties, but they come at a higher cost.



How reliable are aftermarket parts?


Quality varies greatly: The saying "You get what you pay for" rings true here. Some aftermarket parts are inferior because they use lower-quality materials. Even if they don't affect the safety or operation of your car, they may simply wear faster and force a trip back to the garage sooner than expected.



Do mechanics use genuine parts?


Many dealerships require genuine parts for all repairs to uphold the manufacturer's warranty. However, here's a little-known fact: you can choose your own mechanic without voiding your warranty, as long as they're a registered automotive repairer who uses genuine parts.
