German Auto Haus: The Benefits of Using Quality Parts

Proper maintenance is essential in keeping your car running reliably and well. Equally so is using genuine or Original Equipment Manufacturer (OEM) parts. Regardless of the type of servicing your car requires, we advise you use only genuine or OEM parts to keep your car running as the manufacturers intended.


The term OEM stands for Original Equipment Manufacturer, and so OEM parts are those produced by a manufacturer or by an external company according to the car manufacturers specifications. When you use genuine OEM parts, your car’s warranty is preserved while also extending the vehicle’s service life. Compared to cheaper parts, genuine and OEM parts are generally of a higher quality, making driving your car safer and smoother.


Not all aftermarket auto parts are created equal which it why it is important to select only quality parts for your vehicle. There are a number of factors that can contribute to differences when comparing the quality and reliability of genuine OEM parts and cheaper economy parts for the maintenance and upkeep of your vehicle:


  • The quality of raw materials used in genuine and OEM parts is significantly better than aftermarket parts which can vary greatly. For example, the quality and cleanliness of the steel significantly affects the quality and reliability of the end product. Aftermarket parts, manufactured using lower quality steel, degrade faster and often don’t last as long as genuine OEM parts made with higher quality metals.


  • Non OEM part manufacturers may cut corners on the level of quality of other materials used in production. This typically occurs because they want to increase the quantity of products produced to sell more without having to increase production costs. This is often seen where manufacturers use lower quality plastics and seal materials. Lower quality seal materials can cause early seal failure, leading to premature failure of the part and potentially far bigger damage to your vehicle.


  • Economy manufacturers often use lower-grade lubricants. Lubrication is important in reducing friction between car components, as well as preventing corrosion and stabilising structures. The use of low quality lubrication leads to increased operating temperatures which will impact the reliability of the part, shortening the component’s service life.


  • Economy manufacturers often have lower quality standards in the engineering and manufacturing processes. Manufacturing parts involve many processes such as forging, turning, heat-treating, grinding and polishing. Genuine and OEM parts are manufactured under rigorous production standards to ensure longevity and quality. As an example, precision heat-treating may be used to achieve the perfect balance of hardness and durability. With economy parts, there is no guarantee that such high production standards are upheld. Economy manufactures may use lower levels of processes to cut costs and save time, so the products end up being more brittle and less able to withstand constant wear and tear.


  • Genuine and OEM parts manufacturing processes involve additional inspections to ensure safety. Additional inspections are performed at various stages to ensure that the final parts are up to product specifications and standards. However, economy manufacturers often pass over these extra steps to shorten the production time and lower costs.


By using only the best genuine and OEM for your Audi, BMW, Mercedes-Benz, Porsche and Volkswagen vehicles we can assure the materials and manufacturing processes are up to the OEM standards avoiding part failure or premature ageing and giving you the confidence of safety, reliability and longevity.
