CP Piston & Ring Set for Miata BPZ3 - Bore (83mm) - Size (Standard) - Compression Ratio (9.0)

CP Pistons is well-known for making strong internal engine components, and this forged piston and ring set is a prime example for your 1999-2002 Mazda Miata. If you're rebuilding the engine in your BPZ3, these pistons are built to handle the demands of a performance build. They come in a standard 83mm bore size, meaning they're a direct replacement for your original pistons if you're keeping the stock bore, or they're ready for a clean hone if you're going slightly larger. The 9.0:1 compression ratio is a solid choice for many performance applications, offering a good balance between power and drivability without being overly sensitive to fuel quality.

Forged pistons like these are significantly stronger than cast pistons. This strength comes from the manufacturing process, where aluminum is heated and then hammered into shape, creating a denser, more robust grain structure. This makes them much more resistant to detonation and the higher pressures found in modified engines. CP Pistons uses advanced forging techniques to ensure consistency and durability, so you can be confident in their performance. This set includes the pistons and the necessary rings, making it a complete package for your engine build.

When installing these pistons, it's crucial to follow the manufacturer's recommended clearances and torque specifications. Proper lubrication during assembly and break-in is also key to ensuring the longevity of your new engine components. Remember that this part is not CARB approved and cannot be shipped to California.
