5150 AutoSport's CP Carrillo Forged Pistons for the BMW S58 engine found in the BMW G80/G82/G83, X3M, F97 X3M, F98 X4M and G87 M2.
The S58 is an aluminium 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 lightweight and heat dissipation benefits of an aluminium block.
These pistons are a factory replacement; no modification will be needed such as; bore or hone.
These pistons are made by CP-Carrillo to 5150 Autosport specifications using HD-forged high-strength aluminium, which allows them to withstand the higher cylinder pressures and temperatures generated by turbocharging.
