CP Piston & Ring Set BMW/Toyota B48 - Bore (3.2283in) - CR (10.25:1) - Set of 4

If you're rebuilding the engine in your BMW or Toyota B48 platform vehicle and looking for a solid upgrade, this CP Pistons forged piston and ring set is a strong contender. These pistons are built to handle more stress than stock, making them a popular choice for builds that aim for increased performance or durability under demanding conditions. The set includes everything you need for a complete engine build, with four pistons and matching rings ready for installation.

CP Pistons are well-known for their forged construction, which starts with a block of aerospace-grade aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, which is what most factory engines use. These SC7706-4 pistons feature a 10.25:1 compression ratio, which is a common target for many performance builds, offering a good balance between power and drivability. The bore size is 3.2283 inches, ensuring a precise fit within the cylinder walls. This set is designed to be a direct replacement for the factory pistons, simplifying the installation process for a qualified mechanic.

When you're putting an engine back together, especially one that's going to see hard use, using well-built internal components like these CP Pistons is crucial. They are designed to maintain their shape and integrity under high temperatures and pressures. Remember that this set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
