The P-Series part numbers have been con- verted to the new M-Series part numbering system. You will find the current pistons have the new (M-Series) part numbers and the old obsolete pistons have retained the old part number system. The P-Series systemwas based on the English or impe- rial measuring system. The M-Series part numbering systemwas implemented to ensure accuracy for today’s high performance snowmobile motors.
