CP Piston & Ring Set for Mini Cooper S N14 1.6L - Bore (77mm) - Size (STD) - CR (9.5) - Set of 4

CP Pistons is well-known for making strong, reliable internal engine components, and this set of four forged pistons for the Mini Cooper S N14 1.6L engine is a prime example. If you're rebuilding the top end of your N14 engine, whether for performance or to replace worn-out parts, these pistons are built to handle the demands of a well-tuned motor. They come in a standard bore size of 77mm with a 9.5:1 compression ratio, which is a solid choice for many builds.

Forged pistons like these are made from a solid block of aluminum that's heated and hammered into shape, making them significantly stronger and more durable than cast pistons. This strength is crucial for engines that see higher performance levels or are subjected to more aggressive driving. The set includes the pistons and matching rings, so you have the essential components ready for installation. The 9.5:1 compression ratio is a versatile figure, offering a good balance between power and drivability for everyday use or mild performance modifications.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and lubrication procedures to ensure a long service life. Because these are a critical engine component, we recommend consulting your vehicle's service manual or a trusted mechanic for the proper installation process. Please note that this part is not CARB approved and cannot be shipped to California.
