Puff of Smoke Racing -- Porshce Factory Parts Numbering Guide

Porsche Parts Numbering Scheme

Porsche part numbers are in the form aaa.bbb.ccc.dd
aaa = Chassis Type
           note: 900 and 999 apply to cross-platform parts - such as seals, o-rings, gaskets, etc.
           note: the Porsche 911 was originally to be named the Porsche 901, but Audi was using
                     similar numbers at the time, so Porsche changed it to the Porsche 911 to avoid
                     confusion. Parts numbers remained "901" in many cases, however.

bbb = Type of Part
for example, all aaa.116.ccc.dd parts might be clutch parts

ccc = Specific Part
           note: if the part has a left and right version, the 9th number will be odd (for left)
           or even (for right).    i.e. a front left brake rotor might be 901.351.143.60 and the
           right front brake rotor 901.351.144.60

dd = Version or Revision
