Once all the old design are sold the external spring version will be updated in PET as the replacement for all years. Porsche wants to sell all the parts it has bought not just the new improved parts. Order by part # to get the latest design.

Thanks! I take it that there are no interface issues with the tensioner piston heads and paddles and that all three tensioners will have external springs??
If you have the latest number for all three spots that would great. I suppose I can circumvent having to know by showing up at a dealer parts counter and say that I have a MY2001.....just rather verify with an actual builder
