The Difference Between OEM, OES, OEA, and Aftermarket Parts
I found a good post on information for the different standard in parts OEM, OES, and OEA. Most technicians believe they are getting OEM replacement parts, and not understanding how part suppliers have different tiers when going OEM and not supplied by the dealer. There are also companies that build higher quality parts then the OEMs do.
There are also different tiers of parts from the same (OEM) supplier, especially sensors. If you've ever been into building gaming PC's, you've probably learned how RAM chips are classed, and the same applies to sensors. Basically, they're all made the same way at the same time, but then they're separated during testing into different bins (tiers) based on their tested performance, which then
I read it and while I do agree to an extent, talking about Moog was almost like an ad for them. Personally I avoid Moog as they are not what they once were in my experience. In some instances I use dealer sourced because you can see the difference. In sensors, I have seen issues but especially in cat converters for example, OEM Dealer is the only way to go to avoid issues. In certain cases
What you say and what the link says differ. The link claims that OES and OEM parts are identical with the exception of packaging. So if one were to believe the link,one would think they are in fact getting OEM parts when purchasing OES. Are they or not? Info sources?
I realize the site presenting the opine most likely has limited time to provide more details (or the sources of their data). My first thought after reading it was "cute", meaning there's SO much more that could have been said on the topic. I agree that some Aftermarket manufacturers improve on original designs but it has been my experience a vast majority of "non-improved" parts ("copies") are
Jaime where does WorldPac parts play into your scenario? They sell OES parts in OEM packaging. They say they buy the parts from the manufacturer, NOT the dealer. Despite the packaging, many claim the parts are not the same, but if your scenario above is still true today,one would think they HAVE to be OEM quality parts(approved BATCH) if they are in OEM packaging. Confusing.....
Hi Rudy, Yes, it is VERY confusing. I don't know why it must be this way. Your example is an obvious exception to what I witnessed way back when, but having been involved so intimately on the supplier side for a bit, I must wonder about the truthfulness of what we are told. Even while a part of the company, I wasn't always told a 100% true "fact". I'm skeptical about each and every statement…
Hi Michael, This whole spare part deal is confusing to most worldwide. And it has long been intentionally left to believeby spare part suppliers that OES is the OEM part with lower pricing. For example first thing that come to my mind is the VAG DSG clutch plates. Manufactured by LUK for VAG group. Now if we were in in VAG's shoes, i personally highly doubt i would like my supplier to be
