What do the following mean to you.

factory part=

OE part =

OEM part =

Aftermarket part =

I am not talking about the price or quality level, just how do you classify each of the parts.

Lets say a factory part in the automobile manufactures box, I call that a factory part.
Factory parts should have the latest revisions.

A OE part is for the most part the same as a factory part, but there are some differences, lets say some parts from AC-Delco or Motorcraft are many times not a factory part, but sometimes they are.

OEM, this is where it seems that there really is a lot of confusion for many people.
To me all it means is that company, at some point in time built some part for some automobile manufacture that went into the car on the line when being built.

If a OEM built a wiper blade for somebodies new car they can then say they are a OEM parts manufacture and say any part they build is being built by a OEM.
That leads many to think that it is the same part that goes into the factory box.
Many times it is, most times it is not from what I have seen.

Aftermarket, is just that, a aftermarket part, which may or may not be of a good quality, just like a Factory, OE or OEM part may or may not be a good quality.


928 guys are very lucky to have the parts guys we have.
so lets support our vendors.

Factory part, exactly what was originally installed at the factory, no revisions etc.

OE, same, but might include not just what went on a specific car, but available options for that model.

OEM, functional equivalent to a factory part, but maybe a different part number and/or a revised part.

Aftermarket part, something that may fit and might work, but with no vetting by the factory for either.

OEM = Original equipment manufacturer, but could also be seconds that do NOT meet the factory specifications. Still built by the original manufacturer.

In the case of Porsche, factory means supplied in a Porsche box/bag and purchased from Porsche.
I do not use the term OE and I do not know any of the wholesalers (where we get our parts other than Porsche) who use that term very often.
OEM = Original Equipment Manufacture - means that they manufature/manufactured the part direct for Porsche now or in the past. This can mean that the part is not exactly the same as the Factory part in some cases. Still has to be pretty dam close otherwise no one would buy/supply it. In general critical parts tend to be as factory. Secondary parts can be different as long as they do the job at a lower price.
Sometimes dfficult to prove if they were OEM or not. Some are obvious others not so. OEM can come in a Porsche bag from a wholesaler.
There are also differences between the manufactures. Example Continental and Gates - both OEM on the TB for Porsche but some issues with performance.
After market is after market. The Lizard shifter is after market. The PKlamp is after market.

All our products are aftermarket too!

Factory parts - come in a Porsche labelled bag with a 928 (or 927 ) part No.

OEM parts - come from a manfatcurer that made or makes that part for Porsche but will only have their part No. on the bag - eg Zimmerman brake discs or Bosch fuel pumps or Bilstein shocks.

Aftermarket - difficult to define' ISVs from a company that didn't exist when Porsche made the 928 ?

Superclamp, Porkensioner, Rogers fuel hoses - they are to a higher (later) standard than the factory parts. So I would find these difficult to classify in my definition of "aftermarket" Improved factory parts perhaps ????

"OEM parts - come from a manfatcurer that made or makes that part for Porsche but will only have their part No. on the bag - eg Zimmerman brake discs or Bosch fuel pumps or Bilstein shocks."

Not always correct as I get parts termed as OEM in Porsche bags. Never boxes.

factory part= Porsche box or bag

OE part = Real factory part just not in Porsche box or bag

OEM part = Made by same company as real Porsche part, but lower tolerances or finish or something

This is tricky because "OEM" companies may be providing a part they didn't manufacture in the first place.

Aftermarket part = Made by any company at all

GlenL

This is the technically correct definition. It leads to problems when the replacement is not a simple re-branding of the Porsche-provided part but is the manufacturer's reverse-engineered version.

Also, you can be sure that Porsche switches suppliers over time for the same component.

I have been seeing a trend for the local dealers around here to buy bulk fluids and try to sell them to me as factory stuff and at factory prices.

Sorry, but if I am paying $125 for a gallon of transmission fluid, it damn well better be in a factory sealed container, not in a rinsed out (maybe rinsed out) prestone jug.

May very well be the exact same stuff, but I have no way of knowing that, except to take their word for it and that is not going to happen.
I will take the word of any of our 928 parts folks, but not some 25 year old at a dealer parts counter.

Yeah Greg, I'd go somewhere else.....

jpNcos

I would think that there would be some legal issues with that.

They just write bulk in after the part number, not sure how that could illegal.

Revising OEM, apparently a company that supplies valve stem caps to the factory can sell pistons as an OEM.

None of these labels mean that much anymore compared to actual experience using the specific product.
