CP Piston & Ring Set for Honda HH23 - Bore (87.0mm) - Size (+0.5mm) - Compression Ratio (9.0)

Forged from high-strength aluminum alloy, these CP Pistons are built to handle the demands of a performance-oriented Honda Prelude. This set is specifically sized at 87.0mm with a +0.5mm oversize, meaning it's designed to replace pistons that have been bored out to that specific dimension during an engine rebuild. The 9.0:1 compression ratio is a notable figure, indicating a balance between power output and drivability for a naturally aspirated or mildly boosted setup.

CP Pistons is known for their robust construction, and this set is no exception. The forging process creates a denser, stronger piston compared to cast alternatives, making them more resistant to the heat and pressure generated in a performance engine. This is crucial for maintaining engine integrity and performance over time, especially if you're pushing your Prelude beyond its stock capabilities. The included rings are matched to the piston design, ensuring a proper seal within the cylinder bore for optimal compression and oil control.

This piston and ring set is intended for a 1995 Honda Prelude. It's important to note that these are an oversize part, meaning they are designed for engines that have already been machined to accept them. If your engine has not been bored to 87.0mm +0.5mm, these pistons will not fit correctly. This set is not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper fitment and assembly.
