If you are like me, then you like when you can find genuine information from Porsche and not from third party websites or forums. Below are two links to a Porsche website which contains general information about the 944 and the other allows you to download the PET manual for any classic Porsche. The 944 PET manual is split into two model years: 82-85 and 85-88. There is also a 924S PET manual listed for 86-88 model years. These should help when you are trying to find an exact part number or for variations in what Porsche delivered across the model years.
