Supertech Mini Cooper R56 N14 18 1.6T 16V 77mm -5.5cc Dome 9.5:1 Piston - Set of 4 (Excl Rings)

If you're rebuilding the engine in your Mini Cooper R56 with the N14 1.6T engine, a set of performance pistons is a key component for restoring or improving its power. These Supertech pistons are designed to handle the demands of a performance engine build, offering a solid foundation for increased horsepower and torque. They feature a 77mm bore size, which is standard for the N14 engine, and a -5.5cc dome volume that results in a 9.5:1 compression ratio when installed. This compression ratio is a popular choice for many performance applications, offering a good balance between power output and drivability.

These pistons are forged from high-strength aluminum alloy, a process that creates a denser, more durable piston compared to cast alternatives. This makes them well-suited for higher cylinder pressures and temperatures often found in modified or performance-oriented engines. The set includes four pistons, ready to be installed in your engine. Keep in mind that this set does not include piston rings, so you'll need to source those separately. It's also important to note that these pistons are not CARB approved and cannot be shipped to California.

When undertaking an engine rebuild, precision is paramount. Ensure you have the correct tools and refer to your engine's service manual for proper installation procedures, including ring gap settings and cylinder wall preparation. These pistons are a well-built option for anyone looking to enhance their Mini Cooper's engine performance.
