...This is the correct 215mm aluminum Pressure Plate used on the 2.0 liter Carrera 6 engines. The pressure plate is "NLA" (No Longer Available from your local Porsche dealer) and are very difficult to find. I still can get these from Germany (or eBay if you are lucky!) for about 850 Euros...

...The 215mm aluminum pressure plate was rated for the 2.0 liter engines with less than 235 h.p. (approx.) and were later improved with the 225mm pressure plates (the 225mm plates are not vintage correct for the 914-6 GT cars, but work much better!).
