CP Piston & Ring Set BMW/Toyota B58 - Bore (82mm) - CR (11:1) - Set of 6

This is a set of six forged pistons and rings from CP Pistons, specifically made for BMW and Toyota B58 engines. You get six complete piston and ring assemblies, ready to be installed in your engine build. These pistons feature an 82mm bore and an 11:1 compression ratio, designed to handle the demands of performance applications where increased power and durability are key.

CP Pistons are well-known for their robust construction, and these are no exception. They are forged from high-strength aluminum alloys, which makes them incredibly strong and resistant to the extreme pressures and temperatures found in high-performance engines. The 11:1 compression ratio is a popular choice for builds aiming for a noticeable increase in power and throttle response without going to an extreme that might require extensive supporting modifications. This specific bore size is crucial for ensuring a proper fit and seal within the B58 engine block.

When you're rebuilding the top end of your B58 engine, especially for a performance build, using high-quality pistons like these from CP Pistons is essential for reliability and power. They are designed to work with the B58's factory cylinder head and crankshaft, making them a direct replacement for the stock pistons when you're looking to upgrade. Remember that this set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
