I believe the engine tray was fitted by Porsche factory to comply with the tough european drive by noise tests. i.e. it reduces the engine noise outside the car. the downside is that it helps to retain heat in the engine bay which accelerates the hardening of the rubber seals and gaskets leading to premature oil leaks. Does keep the oil of the garage floor though, so mine will stay on until the reseal due at about 140,ooo klm.

The bidding is at $10.50 and has not yet met his reserve. He claims a new one would cost $1,260.15 from the dealer.
Time to become a horder!
Good luck!

Removing the engine tray is a trend in North America. Not so in Europe.
It is also unproven that its removal will help engine cooling. In fact, it may cause uneven cooling of the cylinders.
There has not been any real testing using correct data collection techniques and result analysis to support the theory.

Weren't the 993s the only cars to have these engine trays?
Didn't the 993 cup cars come without these trays?
Aren't the engines and undersides of the 993 and the previous 911 model very similar? I call BS on air not flowing properly and cooling the motor, especially if cup cars didn't have the trays.
If I was concerned about the back end lifting up at speed I'd install an RS spoiler but I really try to keep it under 160 around town.

The CUP cars are different. They are not concerned about how long the engine lasts...
In spite of your BS call, there is still no, repeat NO empirical study using correct data analysis tools and software on the benefits of keeping or removing the undertray...
The bun fight is ON!!! Kidding of course...

That's the truth, per the Porsche factory. Also, the tray, along with all the under sheathing, was counter balanced in the design process of the car to maintain fore and aft weight distribution. Mine has been on since new, mostly in Las Vegas (+100F 8 months out of the year). 90K+ miles, no leaks, no oil consumption, runs cool, no worries. Bad valve guides are caused by, well, bad valve guides.
