OE, OEM and OES (Factory) Auto Parts

Auto parts shopping - particularly for import cars - can be very difficult if you don't understand the differences among brands. Let's clear up some misconceptions so you aren't tempted by some inferior aftermarket parts that can actually do more harm than good - often costing you much more in the form of major auto repairs!

OEM (original equipment manufactured) and OES (original equipment supplied) many times are one and the same. OE, of course, is a more generic term that refers to the brand that came as original equipment on the car. Most auto manufacturers assemble cars from purchased components and manufacture only the sheet metal components.

Therefore, the "factory part" you can buy from your dealer was most likely made by another company, sold to the car maker and then resold to the dealer for ultimate sale to you.

An important point many people are unaware of is the fact that multiple OES brands are not only normal but are actually mandated by international standards as part of the qualifications for ISO certification. Car manufacturers must have secondary sourcing (i.e., multiple suppliers) for certain types of parts in order that any problems with one supplier will not disable the car manufacturer's production and allow for substitution of the other brand for new production and any warranty replacement or repairs.

As an example, the original VDO pump may be interchanged with the Bosch unit with equal performance, the ZKW fog light may be interchanged with the Hella unit or the Balo brake rotors replaced with Zimmermann.

Further, many parts manufacturers are considered OES when, in fact, the exact same parts came on the car under a different brand name. We continue to strive to offer the direct OE replacement under whichever brand name is available.

We deal directly with many OEM/OES companies and stock the exact same parts as your local dealer - usually at substantially lower prices! It may not always come in a package with the car maker's name but it is, in fact, the very same part, manufactured by the very same company.

Why pay for all those middlemen when you can get the exact same part at DSNWParts.com? DSNWParts.com strives to supply one or all of the original equipment brands when available - usually the most commonly used brand is the more available one at a cost savings that we can pass along to you, our valued customer.

That's why our price may be 20%-90% below your dealer's price. You're not skimping on quality - it's the same quality as the dealer's part. You're just cutting out the overhead caused by too many middlemen.
