The "OE" versus "OEM" parts myth

8/21/2014

0 Comments

 
Years ago I had a British gentleman pull up at my shop. Before entering the work area he stood just outside the bay doors and bellowed, "So, is there any trained Technicians here or just men with tools"? I must admit, "That Guy" made a lasting impression.

In terms of "Replacement" parts and the type of billing a factory approved parts list provides, couldn't the same type of question be asked whenever you're trying to decide where to take your car in for repairs?

Believe it when I tell you not only your vehicle, but its individual parts will often try to tell you they're about to fail. Some parts will even try to tell you before leaving their box.

Much could be said here with regards to who the, professionals are in any industry and the details that should elevate them above others.

Due to the increase in technology premature part failure should almost be a thing of the past.  A "Part" that unexpectedly fails under mass production conditions is one thing, whereas a complete unit tha suffers numerous part failures is more telling about the entire manufacturers protocol. The latter usually subsidized by a strong Legal department.

Whenever debating the historical difference between OE parts verses well disguised After Market parts and any possible improvements made to date, I'm skeptical there's enough solid evidence that's also made available to the general public in terms of  the importance of Factory Tolerance Specifications. The type of information that's usually makes for a boring read.

That space were many details either get lost or confused during the Reverse Engineering process. The duly named After Market could be a whole separate write up on manufacturing outsourcing and the on site Quality Control protocol that pales in comparison.

After Market products where the manufacturer of same ultimately wants the end user to trust their attention to detail considering the importance of tolerance specifications. Truth be told, it always boils down to the inadequacies that are Tolerated on a production line in the making of an inferior product.

The lead in sales pitch of some of these individual parts providers might sound like, "After years of Intense study and research, we've Managed to develop...".? Why does any mystery also 'Remain" a mystery?

In terms of Improvements made to a part that's designed to work in conjunction with other parts also in a well Designed designed environment, who should have the broadest perspective of same? The arranged philosophy of the design engineers who were All hopefully on the same page. 

In terms of consumer expectations, is there a true reason the representation of any failure also fails to clearly articulate exactly Why it failed? As if a response to why a product failed "Prematurely"? Once again the Legal Department comes to mind.

In my own estimation of field and industry testing, the "History" of any automotive component requires more than words that suggest rigorous testing. Circumstances where more than the elements and their long term affects can somehow be measured over a specific measure of time that does meet with the approval on the majority of end users? Not only a measure of time combined with the rigors of external stressors, but more importantly consumers expectations that were based on the vagueness of the Guarantee?

It's always easier on the front end to make a successful claim, yet more often than not doesn't it prove to be the back side of the success story that gets to make the closing argument? Its a commonly understood notion in terms of cooking the books, yet statistic's can only speak what's true when there's not a lot of garbage mixed with the "Details" people truly want to trust.

Having information available at purchase is invaluable. Information such as the return ratio of totals sales made to date verses mark up ratio for the retailer.

The type of reliable R&D that's continually evolving once the product leaves the assembly line? The type of quality that also proves worthy by way of minimal failure rate feed back relating to same. A type product that holds true to the Original designers philosophical approach.

I'm of the opinion, product "Outsourcing" has become one the greatest manufacturing riddles to solve. In terms of producing Quality because every aspect of same is kept under the same roof. Could You imagine having access to non-filtered sales data of any product You purchase? That imaginary space where You are well informed?

In this business I get ask a lot of questions and some more frequently than others. I'm often asked, "Do you only use OE or OEM parts" as if there's a "Mutually" understood difference being tabled? The easy response would be to just say "Yes" and move on, yet I know what's really being asked, "Do you only use quality parts"? Once again the response should be as simple as "Yes".

It took me a while, but in terms of working with what's available one thing I had to decide years ago as a Technician was to stop asking "Why" in terms of Mercedes, BMW and the capable engineers who've managed their craft. Managed well enough in order to maintain the philosophical approach in the making of not only industry leading vehicles, but the attention to detail enlisted as compared to other Auto Makers.

The Mercedes Benz and BMW presentation may not always be the most perfect thing one could imagine, but at minimum their automotive engineers have historically proven not only their products but also their progressive approach in terms of remaining on the cutting edge of Automotive Technology "Quality" as compared in the market place.

Rarely will Major Auto Makers mysteriously make "Major" changes to their out sourcing without a reason. Especially true when the original product continues to perform as Originally intended. Don't hear what I'm not saying, because the combined affect of federally mandated recalls, public opinion & class action Law suits speak louder than do well crafted marketing strategies. The type of marketing that revolves around all that public "Perception" needs to believe in order to make the sale.

The type research where billions are spent in Controlled test environment yet few details about their failure ratios after the sale. Many manufacturer's are more than willing to release otherwise useless information that has proven to have very little to do with the performance and longevity of their product once it finds itself in the possession and Control of the end user. Information most consumers know they've compiled.

There's a lot of wisdom in that saying, 'If something isn't broke don't try to fix it" and the same could be said about why the quality of parts are reluctant to continuously rise to the occasion.

It may be true "Not all parts are created equal" yet when the dust settles it usually speaks to the long or short lived philosophy which more often than not eventually dies at the feet of the "Lemon Laws".

Bottom line, if the same part also made by the "Same" manufacturer is available at a more affordable price (which usually comes in unbranded box) it only interprets into common "cents"? That's also to suggest if the manufacturer of a component insist they're fully invested in terms of "Quality Control". If this holds true, they'll also remain at the Apex of the learning curve. 

Playing the guessing game can get expensive, especially in light of how difficult it has become of late to try and get Only the "Facts" as if straight from the "Factory" where it all began? I'm torn between two opinions? Manufacturing parts only for the duration of a factory warranty period or making a product that will sell itself over the "Long Haul".

Are we talking about parts manufacturers that have done their due diligence in order to keep pace with the ever changing industry "Standards"? Or are consumers forever trying to hit a moving target? 

Let's face it, top end Auto Makers will pay a premium price to have their parts boxed, branded and Quality controlled. You would assume manufacturers clearly understand the true potential of their staying power in the Automotive parts industry.

If a consumer wants to use only OE (Original Equipment) they should expect to pay more for that branding. More often the norm for branded products will land somewhere between 15% - 25% higher.

In terms of replacement parts and their OE vs OEM differences the exception might be if a consumer plans on keeping their car until it becomes a "Classic". A status where "Mint Condition" truly interprets as branded "Original Equipment" with zero exceptions.

Buying only OE parts as if the Golden Rule doesn't always interpret "Best" quality or hard a line guarantee of a particular parts life span. Especially when the more telling information has leanings toward documented repairs. The more telling component to include repairs made while a vehicle is under "Manufacturer Warranty". Most consumers will never gain access to the unfiltered version.

I look at this way, if your water pump gets replaced 2 times while under a 4 year 50k mile "Factory Warranty", that part is trying to say something. But if those type of statistics never reach public awareness, truly how valid are the publicized "Statistics"? When dealing with the issue of color matching, part fitment (namely Trim Items) "Original Equipment" is the only way to go.

My philosophy is, try to stay informed through due diligence with regards to specific "Original Manufacturer's " parts providers. If the automaker has since switched individual parts providers, try to find out "Why". especially if you're truly interested in making a well informed vehicle purchase

Keep it simple in when it comes to high volume replacement parts such as brakes, belts, bulbs, fluids and filters. On a much smaller scale, find out if those "Original" parts manufacturers also make these routine parts available to the "Independent" repair industry.

Having a clear understanding as to why any individual replacement parts does retain their prime status in the market place should also point back to "Why" a particular Auto Maker was "Chosen" to begin with.  

​At the end of the day doesn't it all boil down to Who, Why and What we trust the "Most" in terms of the dependable functionality of our "Family" operated vehicles. DL
