They don't say it specifically, but those look like the PD-150 pistons. If that's what they really are, they're supposed to be bullet-proof.

yea they have a small 'circuit' for the oil to flow through and cool the piston... rather than just shooting it at the bottom of the piston.

cool thanks for the reply don't mean to sound like a noob but will they work in all tdi's ?? all the 1.9 tdi's have the same bore/stroke and rod length correct ?

wrist pins on the pd 100-130 are not the same as the 150 and other tdis. Other than that the pistons are about the same. If you are building a VE in the states the pd pistons are a good way to go if you plan on pushing over 250hp with lots of bottle...
