Mahle is one of the top piston maker companies in the world.
Through co-operation with Mahle, Maruha have made these special custom pistons for Miata BP engine. 

Made from phosphate coated forged aluminum (4032) and grafal coatied on the outside and the inside - The end product is not only a strong piston but its also very smooth.

Maruha power pistons are adapted to pin offset position. Off set pin can reduce flap sound and make the engine become very silent. Pin OD is 20mm, the same as stock so using them with stock rods is possible.

Maruha power pistons also have special rings by Mahle. 1st and 2nd rings are 1.2mm thick. Usually American rings are 1.5mm for these size pistons.
As for oil rings, our ring is 2.8mm, American rings are basically 3.0mm.
Thick rings would be a cause of friction however Maruha wanted to avoid any friction to make the piston's work smooth and to get more power.

This total balance leads to the piston's long life, minimum oil consumption, silent engine and more power!

BP (1.8) stock 83.0mm --> Mahle 85.50mm
