A Debate Over A/M v OEM Parts
Discussion
I did some work on the engine in my LR over the summer. I (unknowingly) used an after market rear crank oil seal. Unsurprisingly it leaked terribly, which meant I had to take the engine back out to replace it. The proper part came with grease, instructions etc. Same with the oil sump gasket, the after market one was thin and came folded up, the proper one was about twice as thick and came on a hardboard base. Again, guess which one leaked?
It depends doesn't it. A recent example on my part is the M Sport suspension on the Z4, prone to cracked springs. I stuck aftermarket Eibach on and it's much better to drive and no doubt the springs are much harder wearing. Much cheaper too.
OTOH, I see what Ford are getting at here.
Depends what after-market we are talking i.e. replica wheels seem pretty crap.

I imagine that there are some good A/M parts and some bad ones. With OEM, you always know its of a certain quality.
However, I thought it was a bit strange when they chose to saw the bumper beam in half to demonstrate how good it is???
A better test would have been impact resistance or how it deforms under pressure.

If you read the viewer comments, the suggestion is made that there were tests, but the results were better than they were hoping. A better test would have been impact resistance or how it deforms under pressure.

Thanks for contributing---
My own experience is that there's definitely a wide variation in quality of after market parts, some are OK some will barely last you till the next MOT.
You know what the end result of more and more bad quality parts will be of course - more new laws, yay!
That new crash center is something Ford is desperately in need of. Making cars crash resistant and cheap to repair is somethign they a incrediably poor at. Ever wondered why Mondeo's always have gaffer tape on the bumpers ? Mondeos and foci have some of the highest crash repair costs out there.
I also laughed very hard when I say that F150 truck. Compare the 5mph into pole crash test of a F150 and a Lexus Ls430
Ford - 2000 dollars damage http://www.youtube.com/watch?v=qivKhDbx_2o
Lexus - no damage - http://www.youtube.com/watch?v=x1E8dSNX8qk

Some interesting/questionable "destruction tests", but the viewer comments are heating up...
Porsche brakes aren't made by Porsche, they're made by an OEM...Some interesting/questionable "destruction tests", but the viewer comments are heating up...
and IIRC there are differences (on a 964 at least) between the Porsche boxed items and the OEM boxed items . . . . . IIRC its only something as silly as the Porsche parts have the hubs painted

I wouldn't say 'no damage' was done to that Lexus, just less obvious damage. The bumper has a noticeable rise on the top surface where the pole has distorted the plastic, you can see this as the vehicle rolls away. Also I would not be surprised if the supports or mounting points which are not visible without removing the bumper have also been shoved out of alingment and possibly some damage to the valence panel behind. After working for a few years in a body shop I know I have seen cars that have taken an impact that look like they have come out unscathed and then you lift the boot floor carpet and it's bent like a wet piece of cardboard.

I once bought Aftermarket drive shafts and rather than being solid it was hollow, it wasn't balanced either and caused vibrations. It's fair to say some non OEM stuff is ok but there is some proper crap out there also, I've seen wings with swage lines that dont even line up with the other OEM panels or when fitted to line up with everything else leave panel gaps an inch wide.
For my motors I buy the parts that the manufacturer uses...... for example Citroen uses Valeo/Bendix etc....so I would get them from GSF... Same parts as O.E but not in a Citroen labeled box.....I do that even for my Mazda grey import.....you don't have to buy 2nd rate parts, do like I do, buy the O.E parts that are in the makers box not the car manufacturers...
I don't know Nitron seem to be doing ok with upgrades to this little Lotus

I'd be of the opinion that any replacement part they produce would be superior to the original part it replaced.
I'd quite like the front uprights but a touch to much for me, do look rather nice though.

Isn't it because old Mondeos had crap rear bumpers prone to cracking? Also, the focus has such a low Insurance Group partly due to the cheapness of repairs.In one of the many boring magazines we get at work, there was an article about this sort of thing.
3 springs. One was a genuine VW part, another was an OEM part, and the other was an aftermarket cheapo part.
The VW and OEM springs were exactly the same. Same amount of coils, same winding, same length.
The cheapo one however, was completely different. To start, the steel was much thinner, about half the thickness. The coils were all over the place, and had a different winding. The only thing that it did right was it was the right length, and had the right sized coils at the top and bottom.

I think some people are confused about pattern parts.
Most car manufacturers get outside companies to make a hell of a lot of their parts, getting them without the "volvo" badge can save over a hundred pounds, yet the parts is made in exactly the same factory and by the same people as the oem one.
The most telling thing about the bulls
t video is they test how the pieces come apart, not how they compare in an accident situation. This to me says that the differences in performance aren't enough to convince you to insist on oem parts.
