Tech Notes
This is the Cylinder and Piston Assembly for the
O.S. Max 12TZ 12TZ (P) Speed Tuned Engine.


ABL (Advanced Bi-metallic Liner) This process uses a double layer of
plating material rather than one thick layer. This helps the metal
bond to the cylinder and is more durable. Also, the plating process
is more consistent, resulting in a more precise fit between
piston and sleeve for better compression, longer life.

Bore: 0.543" (13.8mm)
