Why Choosing Original Equipment Manufacturer Parts Matters for Long-Term Performance and Reliability
German vehicles are known for their precision engineering, advanced performance systems, and longevity—but only when they are maintained with equal precision. One of the most critical decisions a German car owner can make is choosing where to service their vehicle and which parts to use. For anyone seeking services for German auto repair in Portland OR, OEM and OEM equivalent parts play a critical role in ensuring reliability, safety, and performance. When working with experts like Trafton’s Foreign Auto, drivers benefit from specialized training, premium parts, and exceptional craftsmanship.
This blog explores why OEM parts are in most cases superior, how they impact long-term vehicle performance, and why professional German auto repair shops like Trafton’s Foreign Auto rely on high quality parts to deliver industry-leading results.
Understanding OEM Parts in German Auto Repair
OEM parts—Original Equipment Manufacturer components are built by the same companies that produced the factory-installed parts in German cars. Unlike aftermarket alternatives, these components are designed to match the vehicle’s exact specifications in material quality, durability, fit, and long-term reliability. Their precision makes them essential for preserving the engineering integrity that German vehicles are known for.
Many independent shops have the ability to order the part through the manufacturer, rather than the dealership. For example, most parts are not actually made by the vehicle manufacturer, such as Porsche, which does not make their struts, shocks, or other suspension components, instead they are made by other companies, then branded as Porsche. The brands when ordered from the manufacturer will typically have the manufacturer name such as Arnott, Continental, Sachs etc. This is a great way to accomplish the same quality at a lower price.
Why OEM Parts Matter for German Cars
German cars such as Audi, Porsche, Volkswagen, Bentley, Mercedes, and Lamborghini are built with highly advanced electrical systems, tight mechanical tolerances, and performance-sensitive designs. Because of this complexity, OEM parts are the only components that reliably integrate with onboard electronics, maintain the accuracy of engine diagnostics, and help prevent premature wear or unexpected safety issues. Professional Repair Services rely on OEM parts because even minor variations in aftermarket components can disrupt the performance and reliability of German import vehicles.
Misconceptions About OEM Parts
Many drivers assume OEM parts are always more expensive, but this isn’t necessarily the case. While pricing may vary depending on economic factors or material sourcing, OEM components often reduce long-term costs by preventing repeated repairs and ensuring proper system functionality. OEM parts do not always mean that the part will be stamped with Volvo, BMW, Porsche, Mercedes etc. OEM parts are made by the original part manufacturer, with the same specs as the part sold directly to vehicle manufacturer.
Why OEM Parts are Essential for Preserving Vehicle Value
German cars are renowned for retaining value when properly maintained. OEM components support this by ensuring the vehicle stays as close to factory condition as possible.
The Role of OEM Parts in Restoration Services
For clients restoring air-cooled classics or undergoing Porsche builds, OEM parts are often considered mandatory. They preserve originality, ensure authentic performance, and maintain matching number parts where applicable.
Improved Resale Value
Buyers prefer vehicles serviced with OEM components because:
- They last longer
- They maintain factory performance levels
- They ensure proper fit and function across all systems
OEM parts directly impact customer satisfaction and long-term reliability.

If OEM Parts Are So Great, Why is My Car Broken?
Even though your vehicle was built with OEM parts, wear and tare will eventually take a toll on these components. Most parts on your vehicle will eventually break. Gaskets get hard and weathered, injectors get clogged, suspension joints wear out, boots tear and so on. Even though an aftermarket part may be of equivalent quality, many OEM parts go through what is called a Superceded Part Number Change. This is when the original part engineer makes a correction or improvement to a component, typically making the original design obsolete from the manufacturer.
Fit & Compatibility
OEM parts are manufactured to match the original components precisely, ensuring a perfect fit the first time. This accuracy reduces labor time, prevents installation complications, and enhances the effectiveness of essential car care services such as engine repair, brake inspections, brake system maintenance, engine rebuilds, and cooling system service. With OEM components, technicians can perform repairs with confidence, knowing every part aligns with the vehicle’s designed tolerances.
OEM Support vs Aftermarket Support
In the even a part is replaced with an aftermarket component, not original to the vehicle, there is often less technical support for these types of parts. Vehicle manufacturer diagnostic and programming tech support will typically not help with troubleshooting if there are aftermarket components within the failing system. This may also jeopardize the vehicles warranty if they component is not made by the original part manufacturer.
Why Professional German Auto Repair Shops Prefer OEM Parts
Why Professional German Auto Repair Shops Prefer OEM Parts
Professional German auto repair shops rely on OEM parts because these components are engineered to match the exact specifications, tolerances, and performance standards of German vehicles. Shops like Trafton’s Foreign Auto understand the precision with which German import vehicles are designed, which is why OEM components remain their first choice for services that demand accuracy and consistency. Whether performing Full-service repair, Maintenance Packages, or restoration services, technicians depend on OEM parts to ensure every repair aligns with the vehicle’s original engineering.
Are All OEM Parts Better Than Aftermarket?
Simply no. There are many OEM parts that commonly fail on vehicles. There are several specialty manufacturers that have made improvements to these commonly failed components. VW Audi branded cooling components that commonly break are typically made of plastic, however some aftermarket manufacturers have redesigned these components to be made from metal. For example, VW, Audi, and Porsche made several models with water pumps that had plastic impellers. These impellers get hot, brittle and eventually crack, causing coolant to not pump, and the vehicle to overheat. Aftermarket manufacturers have redesigned these pumps to no fail, therefor avoiding catastrophic engine failures.
It is important to work with an experienced shop that is familiar with part brands and pattern failure. Being educated on part redesigns is so important to extending the life of your vehicle.
