Supertech BMW B48 2.0T 16V 82.5mm (+0.5) 33.2mm CH 11:1 CR Piston - Set of 4 (Excl Rings)

Supertech is a well-known name for performance engine components, and this set of four forged pistons for the BMW B48 2.0T engine continues that tradition. These pistons are designed for builders looking to get the most out of their B48 engine, offering a robust upgrade over stock components. They feature a bore size of 82.5mm, which is a 0.5mm oversize from the standard bore, and a compression height of 33.2mm. The 11:1 compression ratio is ideal for a balance of power and drivability in many performance applications.

Forged pistons are significantly stronger than cast pistons, making them a popular choice for engines that will see higher boost pressures or more aggressive tuning. This strength allows them to withstand the increased cylinder pressures and temperatures associated with performance modifications. The specific design of these pistons, including their compression ratio and dimensions, is intended to work within the B48 engine's architecture for a direct fit in terms of piston-to-cylinder wall clearance and valve relief depth. Remember that this set does not include piston rings, so you will need to source those separately to complete the installation.

When rebuilding or modifying your BMW B48 engine, choosing reliable internal components is crucial. This set of Supertech pistons offers a solid foundation for a performance build. Ensure you have the correct ring set and consult your engine builder or service manual for proper installation procedures, including ring gap settings and lubrication requirements. Please note that these pistons are not CARB approved and cannot be shipped to California.
