CP Piston & Ring Set BMW/Toyota B58/B48 - Bore (3.2283in) - CR (10.25:1) - Set of 6

CP Pistons offers this set of six forged pistons designed for BMW and Toyota B58 and B48 engines. These pistons are built to handle the demands of performance applications, featuring a bore size of 3.2283 inches and a compression ratio of 10.25:1. Forged pistons are known for their strength and durability, making them a solid choice when rebuilding or upgrading an engine where increased power output or reliability under stress is a goal.

The construction of these pistons uses high-strength aluminum alloys, which are forged under extreme pressure to create a denser, more robust grain structure than cast pistons. This process results in a piston that is significantly more resistant to deformation and failure, especially under high cylinder pressures and temperatures common in performance tuning. The specific design of these pistons takes into account the unique characteristics of the B58 and B48 engine platforms, ensuring proper fitment and function. This set includes the pistons and rings, providing a comprehensive solution for engine assembly.

When undertaking an engine build with these pistons, it's important to ensure all supporting components are up to the task. This includes proper balancing of rotating assemblies, appropriate cylinder wall preparation, and correct ring gap settings according to CP Pistons' specifications. Because these are performance-oriented components, careful attention to detail during installation is crucial for achieving optimal results and long-term reliability. Always refer to the manufacturer's installation guidelines for precise details on clearances and assembly procedures.
