CP Piston & Ring Set for Accura/Honda B-Series - Bore (85.0mm) - Size (+1.0mm) - Compression Ratio (

CP Pistons is well-known for making strong, reliable internal engine components for performance applications. This piston and ring set is built for the B-series engines found in many popular Honda and Acura vehicles, including your 1988-2000 Honda Civic. If you're rebuilding your engine or looking to handle more power, a set of forged pistons like these is a solid choice.

These pistons are forged from high-strength aluminum, a process that creates a denser, more durable part than cast pistons. This makes them better suited to withstand the increased cylinder pressures and temperatures that come with performance modifications or heavy-duty use. This particular set is 85.0mm in bore size and is 1.0mm oversize, meaning it's designed to be used when the cylinder walls have been bored out to match this dimension during an engine rebuild. The compression ratio is also specified, which is crucial for tuning your engine's performance. This set includes the pistons and the necessary rings to complete the assembly.

When rebuilding an engine with oversized pistons, it's essential to ensure your cylinder walls are properly machined to the correct bore size. Always refer to the manufacturer's installation instructions for precise details on fitting these pistons and rings to your B-series engine. Please note that this part is not CARB approved and cannot be shipped to California.
