Bore Size: 87.0mm This refers to the diameter of each piston, slightly larger than the stock bore (which is typically 86.4mm). The increase in bore size slightly raises displacement and allows for better airflow and combustion, improving power potential. Dome Volume: -10.10cc The negative dome volume indicates that the piston has a dish shape, rather than a positive dome. This affects the engine's compression ratio and helps with fine-tuning cylinder pressures. A dished piston like this allows for higher performance at high RPM, while maintaining stability. Compression Ratio: 11.50:1 This high compression ratio is ideal for naturally aspirated performance applications, offering more power output by increasing the efficiency of the combustion process. A higher compression ratio helps the engine generate more horsepower and torque from the same displacement. Material: Forged aluminum JE Pistons are known for their high-quality forged aluminum construction. This offers better strength and durability under high stress and heat, making them suitable for high-performance and racing applications. Application: BMW S50B32 (Euro-Spec E36 M3) This kit is specific to the Euro version of the S50 engine, which differs slightly from the US-spec version in terms of displacement, power output, and other engine characteristics.
