Replacement of car parts

Introduction

When it comes to car repairs, you can’t simply put in a replacement part without knowing its benefits. You must always ensure that you’re getting exceptional components for reliability and consistent performance.

OEM, or original equipment manufacturing, parts are your go-to alternative for quality and durability. They are manufactured to offer identical performance to that of the original parts. If you’re still unaware of their benefits, here’s a guide just for you.

Learn here why going OEM is a good investment for your vehicle.

Benefits Of Using OEM Parts On Your Vehicle

Most of the time, mechanics will recommend OEM auto parts due to a range of benefits. These perks make OEMs a great value for money, making it hard for car owners to overlook their value.

1. Quality Assurance

One of the leading selling points of OEM parts is their strict adherence to quality. OEM manufacturers are bound to be rigorous in quality checking to meet the standards of car manufacturers.

They have a precise system of design, testing, and producing parts to meet the original part specifications. To guarantee superior quality, OEM manufacturers invest in extensive testing. They not only mimic the parts’ accurate dimensions but also ensure their reliability. Every OEM component goes through performance evaluations and durability assessments. They also run these parts through stress tests.

On top of that, OEM manufacturers must also abide by market standards and international safety regulations. All these parameters lead to a product with superior integrity, longevity, and performance. It’s safe to say that OEM manufacturing does not cut corners in providing reliable automotive parts.

2. Perfect Fit

Compatibility is key to ensuring the optimal performance of replacement parts. OEM offers replacements that are tailor-made for your specific vehicle brand and model. These parts are also suitable without further modifications.

Only car manufacturers or their licensed suppliers can produce these parts. Hence, they follow the precise design and dimensions of the original parts. You can rest assured that OEM products are engineered the same way the original parts were.

Unlike aftermarket car parts, OEM tailors the performance of original parts to the same. You can install it without a hitch and expect the same efficiency and function.

3. Warranty Protection

Another advantage of OEM automotive parts you can’t overlook is their warranty protection. This is a standard guarantee that comes with every OEM part you buy. You’ll get protection from defects and premature failure without the extra cost.

You’ll usually get a coverage period of 1 year or more, depending on the parts you bought. Besides the parts warranty, your car’s overall warranty also doesn’t get affected. Unlike aftermarket components, your car’s warranty, or aspects of it, doesn’t get void if you use OEM.

This perk leaves you confident and safe from costly, unforeseen repairs. You can have peace of mind knowing you’re protected from hefty costs.

4. Longevity

No one wants to replace their original parts with temporary components. As much as possible, you must invest in durable replacements you can rely on in the long run. You can turn to OEM parts for this concern.

As mentioned earlier, OEM parts ensure quality checks and compatibility. OEM follows strict manufacturing standards that guarantee quality identical to the original components. They use premium materials through advanced manufacturing techniques for long-lasting durability.

Further, OEM’s compatibility eliminates unnecessary strain on the component. Since the part is precise, it also functions with accuracy, avoiding premature wearing. This efficient and balanced performance contributes to prolonging the part’s lifespan.

5. Better Performance and Efficiency

What happens when you get a replacement part just as good as the original part? You get superior performance and ideal efficiency.

OEM parts are identical in quality and fit to the original components, so they also function identically. You can depend on them to function as well as your default component. OEM guarantees exceptional performance through its precise engineering.

These precision parts leave no room for any change or modifications. It fits precisely; hence there are minimal to zero performance issues to worry about. Sometimes, OEMs are even cast from more durable materials. This way you can get better durability and performance for a longer period. In the end, you’ll feel no compromising function and efficiency problems in your vehicle.

OEM vs. Aftermarket Parts

OEM parts are often pitted against aftermarket components. In most cases, the OEM makes the better choice. However, aftermarket parts also offer some advantages. Here’s a breakdown of their perks and drawbacks.

Pros and cons of OEM parts

OEM parts are the first choice if you’re looking for compatibility and unmatched quality. Aftermarket parts can’t match it in these areas. However, there are still drawbacks despite these undeniable perks. OEMs come with a more expensive price tag for starters. They are also less available and limited in variety.

There’s also manufacturer dependence. As said, OEM components are tailored to the make and model of your automobile. If a part is discontinued, you may have to search for used or aftermarket alternatives. And if you’re into performance boost, OEM offers no guarantee since it’s after the original function.

  • Perfect Fit and Compatibility
  • High Quality and Durability
  • Warranty Protection
  • Safety and Performance
  • Resale Value
  • Manufacturer Support

Cons

Pros and cons of aftermarket parts

Despite OEM’s remarkable offerings, aftermarket auto parts are still high in demand. And they are for several reasons.

This leads to the pros of performance boost that most auto enthusiasts are after. Many turn to aftermarket components for performance upgrades. This is made possible since they are more customizable and modifiable.

Add to that them being also a practical option for quick fixes. Since they are more available, you can buy them for temporary and faster repairs.

On the other hand, several drawbacks also loom over these aftermarket perks. Inconsistent quality and fitment issues are a constant concern when buying aftermarket components. This means you’re not promised to get proper durability and performance. And while they can be a quick fix, you’ll never get manufacturer’s support or warranty. And the worst part is that your car’s warranty can be voided should you go for this alternative.

It’s clear that both OEM and aftermarket auto parts have distinct offerings. One fills the void the other can’t fill. But, the final choice ultimately depends on your needs and the purpose of replacement. To give you a better guide, here’s a practical tip on when to buy an OEM or aftermarket part.

New cars and under warranty

If you’re afraid of voiding your existing warranty, go for OEM. They come with a manufacturer’s warranty and do not void your car’s warranty.

On a budget

Aftermarket parts are your clear choice here. They are a cheaper option and are more available in different varieties you can modify. They retail for less, sparing you the premium markups and branding costs.

Safety comes with strict manufacturing standards. Turn to OEM parts if you’re after critical safety of your car. Their rigorous quality assurance and adherence to regulations guarantee their unmatched safety and reliability.
