CP Piston & Ring Set for Acura B18C1 - Bore (83mm) - Size (+2.0mm) - Compression Ratio (9.8)

CP Pistons is well-known for making strong internal engine components, and this piston and ring set is a prime example for your 1994-2001 Acura Integra with a B18C1 engine. If you're rebuilding the top end of your engine, especially if you're looking to increase displacement or refresh worn components, a set of quality pistons like these is essential. This set is designed to be a +2.0mm over bore, meaning the cylinders will be honed to 83mm to accommodate these pistons, effectively increasing the engine's displacement.

These pistons are forged, which means they start as a solid block of aluminum that is heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for performance applications or engines that see hard use. The 9.8:1 compression ratio is a notable figure, indicating how efficiently the engine will compress the air-fuel mixture. This ratio is often chosen for a good balance between power and reliability for many performance builds. The set includes the pistons and the necessary rings, ready for installation after your engine block has been properly machined to the correct bore size.

When installing these pistons, ensure your engine block has been professionally bored and honed to the specified 83mm size. It's also important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for proper assembly and break-in procedures to ensure the longevity of your engine build.
