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

This is a complete set of four forged pistons and matching rings from CP Pistons, specifically made for Honda B-Series engines. You get everything needed to replace your pistons and rings in one package, designed for an 84.0mm bore and offering a 12.5:1 compression ratio. This set is intended for enthusiasts looking to rebuild or significantly upgrade their B-series engine, commonly found in popular Honda and Acura models.

CP Pistons are well-known in the performance engine building world for their robust construction and attention to detail. These pistons are forged from high-strength aluminum alloy, which makes them significantly stronger and more durable than cast pistons. This strength is crucial for handling the increased cylinder pressures and temperatures that come with higher compression ratios and performance tuning. The 12.5:1 compression ratio is a notable bump over stock, designed to extract more power and responsiveness from your engine, especially when paired with appropriate camshafts and tuning. The set includes the pistons themselves and the necessary rings to properly seal the combustion chamber, ensuring optimal performance and longevity for your rebuilt engine.

When installing these pistons, it's important to follow the manufacturer's detailed installation instructions, as precise clearances and ring gapping are critical for proper function and engine health. This set is a substantial upgrade for anyone serious about building a high-performance B-series engine. Please note that this part is not CARB approved and cannot be shipped to California.
