Supertech BMW B58 82mm Bore 36cc 10.2:1 CR Pistons - Set of 6 (Excl Rings)

Supertech is well-known for making robust engine components, and this set of forged pistons for the BMW B58 engine is no exception. If you're rebuilding or upgrading your B58 engine, these pistons are designed to handle increased performance demands. They feature an 82mm bore and a 10.2:1 compression ratio, which is a popular choice for many performance builds aiming for a balance of power and drivability.

These pistons are forged from high-strength aluminum, a process that creates a denser, more durable material compared to cast pistons. This makes them more resistant to the stresses of higher cylinder pressures and temperatures often found in tuned or performance-oriented engines. The 36cc dish volume is specific to achieving that 10.2:1 compression ratio when paired with the correct cylinder head and gasket combination. It's important to note that this set includes the pistons only; you will need to source piston rings separately to complete the installation.

When installing these pistons, ensure you follow the manufacturer's recommended clearances and lubrication procedures. Proper installation is key to realizing their full potential and ensuring long-term reliability. Because these are not CARB approved, they cannot be shipped to California. Always consult your engine builder or a qualified mechanic to confirm compatibility with your specific build plans and ensure all necessary components are accounted for before starting your project.
