FS: @eBay -NOS Genuine Porsche Mahle piston/cylinder set for '69 911E 2.0 w/ 9.1:1 CR
This is Porsche part number 901.103.909.02 and this is a "Group 6" set (this same part number ending in 01 instead of 02 would be a "Group 5" set). These are new and never used, each cylinder is still in their original Porsche plastic bags, and in perfect new condition with no corrosion.
Also included are six new base gaskets and a set of Deves piston rings. Opening price is $1999 with no reserve:

I got this set in a parts lot with a '66 911 I recently purchased. The owner was a mechanic, and had some random parts he stocked for Porsches in the shop he owned.
