CP Piston & Ring Set for Acura B18A/B1 - Bore (81.0mm) - Size (STD) - Compression Ratio (9.0)

When you're rebuilding the heart of your 1990-2001 Acura Integra, starting with a solid set of pistons is key. This set from CP Pistons includes four forged pistons and the necessary rings to match, all designed for the B18A and B1 engines. They're built to handle the demands of a performance build, offering a 9.0:1 compression ratio that's a good starting point for many engine builds.

CP Pistons are known for their well-built forged construction, which means these pistons are significantly stronger than cast aluminum. This strength is crucial for engines that see higher performance use, helping to resist detonation and withstand increased cylinder pressures. The pistons in this set are machined to an 81.0mm bore size, which is the standard size for many B18A/B1 applications, ensuring a proper fit within the cylinder walls. This set is a popular choice for Integra owners looking to refresh or upgrade their engine internals.

This kit comes with the pistons and rings you need to get started on your engine build. Remember that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
