CP Piston & Ring Set BMW/Toyota B48 - Bore (3.2283in) - CR (11.0:1) - Set of 4

This is a set of four forged pistons and rings from CP Pistons, specifically made for BMW and Toyota B48 engines. These pistons are designed with a 3.2283-inch bore and an 11.0:1 compression ratio, making them a solid choice for rebuilding or upgrading the engine in your performance-oriented BMW or Toyota vehicle. CP Pistons is well-known for producing strong, reliable engine components for demanding applications.

Forged pistons like these are built from a solid block of aluminum that's heated and hammered into shape, which creates a much stronger and more durable piston than cast alternatives. This strength is crucial for engines that see higher cylinder pressures, whether from forced induction or increased compression. The 11.0:1 compression ratio is a notable increase over stock for many B48 applications, which can lead to improved power output when paired with appropriate tuning. The included rings are designed to seal effectively against the cylinder wall, ensuring good compression and oil control.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and torque specifications to ensure proper break-in and long-term reliability. This set includes all four pistons and their corresponding ring sets, ready for installation into your B48 engine block.
