Description

BMW S58, G80/G82/G83, X3M, F97 X3M, F98 X4M, G87 M2

The S58 is an aluminum block with a spray-on iron coating on the cylinder walls. This allows the engine to have the strength and durability of a cast iron block, while still retaining the light weight and heat dissipation benefits of an aluminum block.

These pistons are a factory replacement and no modification will be needed such like; bore or hone.

These pistons are made by CP-Carrillo using HD forging made of high-strength materials forged aluminum, which allows them to withstand the higher cylinder pressures and temperatures generated by turbocharging.
