CP Piston & Ring Set for Acura/Honda B16A - Bore (84.0mm) - Size (STD) - CR FT (Set of 4)

This is a set of four forged pistons and rings from CP Pistons, specifically made for Acura and Honda B16A engines. These pistons are designed to fit a standard bore of 84.0mm, which is the original size for many B16A applications. If you're rebuilding the engine in your B16A-powered vehicle, whether it's a performance build or a restoration, a solid set of pistons is crucial for reliable power and longevity.

CP Pistons are well-known in the performance engine building community for their robust construction. These particular pistons are forged from high-strength aluminum alloy, a common choice for performance applications because it offers a good balance of strength and weight. Forging involves shaping the aluminum under extreme pressure, which aligns the grain structure of the metal, making it much stronger and more resistant to detonation and fatigue than cast pistons. This means they can handle the increased cylinder pressures and temperatures often found in modified or high-performance engines. The set includes the necessary rings, which are also selected to work with these specific pistons for a proper seal.

When installing these pistons, it's important to ensure your cylinder bores are perfectly clean and within the specified tolerance for a standard 84.0mm bore. Proper ring gap setting and lubrication during assembly are also key to their performance and lifespan. Keep in mind that this piston set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for precise specifications and procedures.
