Just met a local fellow with a 993 Turbo S and it has this additional Front Oil Cooler.
It mounts just below the A/C condenser on the Drivers side.
He claims its very effective and offered me numbers to show the temp drop.
Now that I know the benefit, I can say for certain this works. Will get photos of his to show others.
Still available. Price $1200 plus FedEx shipping worldwide.
