CP Piston & Ring Set for Mini Cooper S N14 1.6L - Bore (77mm)-Size CR (9.5.1)-Set of 4

CP Pistons is well-known for making strong, reliable engine components for performance applications. If you're rebuilding the top end of your Mini Cooper S with the N14 1.6L engine, this set of four forged pistons and rings is built to handle the demands of a performance build. These pistons are designed with a 77mm bore and a 9.5:1 compression ratio, making them a solid choice for engines that might see higher performance use or modifications.

Forged pistons like these are made from a solid block of aluminum that's heated and hammered into shape under extreme pressure. This process creates a much stronger and more durable piston than cast ones, which are poured into a mold. This strength is crucial for engines that are pushed harder, as it helps them resist deformation and cracking under high cylinder pressures and temperatures. The 9.5:1 compression ratio is a common target for many performance builds, offering a good balance between power and drivability, and it's often chosen when an engine might be turbocharged or supercharged.

This set includes all four pistons and their corresponding ring sets, so you'll have everything needed to replace the pistons in your N14 engine. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
