Boston Motor Werks is a strong believer in Original BMW parts, fluids, and accessories. Through our years of experience at both the dealer and independent shops, nothing has provided better quality, reliability, and longevity than factory original parts. We stand behind our workmanship and parts because of this reason. Various aftermarket parts we find have shorter lifespans and poorer performance to match their lower costs.
First, we must define what an aftermarket part is. A lot of suppliers use the term ‘OEM’ or ‘OES’. However, the terms OEM and OES can cause a bit of confusion, as they refer to Original Equipment Manufacturer or Original Equipment Supplier. They do not mean ‘OE’, or Original Equipment. Yes, there is a difference, and sometimes a really big difference. Original Equipment is a factory BMW part, i.e. has the BMW stamp on the part and is the part that is installed at BMW’s assembly line. OEM or OES is that supplier’s part that they do NOT supply to BMW’s assembly line; it is that company’s part that they sell to the general public. Now, not all of these parts are bad or defective, but many of them are a far cry from the quality of the parts that carry the BMW stamp.
The old aged mantra ‘you get what you pay for’ definitely applies to parts. People tend to be attracted to aftermarket parts mainly for their lower costs. Those lower costs frequently bring with them lower or sub-par performance. When these parts fail pre-maturely, you will have to bring your car to the shop again and will be paying for labor to replace the item again, thus spending more money, time, and effort than if the job was done right the first time. And that is if that poor quality part did not leave you stranded on the side of the road. They are counter-intuitive. Ultimately you will end up spending more money to do the job again, which defeats the purpose of buying the cheaper part to begin with. We believe in doing the job right the first time.
