CP Piston & Ring Set for Honda B-Series - Bore (84.0mm) - Size (STD) - CR (12.5) - Single

CP Pistons is well-known for making strong, reliable internal engine components. This forged piston and ring set is built for Honda B-Series engines, specifically designed for a standard bore of 84.0mm with a 12.5:1 compression ratio. If you're rebuilding the top end of your B-Series engine and looking for a well-built piston that can handle increased performance demands, this set is a solid option.

Forged pistons like these are made from a solid block of aluminum that's heated and hammered into shape, making them significantly stronger and more durable than cast pistons. This strength is crucial for engines that see higher cylinder pressures, whether from forced induction or higher compression tunes. The 12.5:1 compression ratio is a notable bump over stock, which can increase power output when paired with appropriate tuning and fuel. This set includes the pistons and the necessary rings to get your engine back together.

Please note that this piston set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
