CP Piston & Ring Set for Honda B18A/B w/B16A Heads - Bore (81.5mm) - CR (9.8) - Dome (-3.7cc)

When you're building a high-performance Honda engine, you need components that can handle the stress. This CP Pistons forged piston and ring set is designed for Honda B18A/B engines when fitted with B16A cylinder heads. It includes four forged pistons and a complete set of high-quality piston rings, ready to be installed in your engine build.

These pistons are forged from aerospace-grade aluminum, a strong and lightweight material that stands up to extreme cylinder pressures and temperatures. They feature a specific dome design with a -3.7cc volume, which, when paired with B16A heads on a B18A/B block, results in a 9.8:1 compression ratio. The bore size for this set is 81.5mm, a common size for B-series engine builds that require a slight overbore. The included rings are designed to provide a solid seal for optimal compression and oil control under demanding conditions.

Building an engine like this often involves more than just pistons. Make sure you have all the necessary supporting components, such as bearings, gaskets, and a complete engine rebuild kit, to ensure your build is done right. Refer to the manufacturer's installation instructions for specific details on fitting these pistons into your engine.
