CP Piston & Ring for Honda B-Series Bore 85MM Size +1.00MM Compression Ratio 12.5 SINGLE PISTON

Forged from high-strength aluminum alloy, this CP Pistons single piston is built for Honda B-Series engines with an 85mm bore, specifically sized at +1.00mm oversize. It features a 12.5:1 compression ratio, making it suitable for builds aiming for increased power and performance. The robust construction is designed to handle the higher stresses found in performance applications.

This piston is a well-built component for engine rebuilding or performance upgrades. The +1.00mm oversize means it's intended to replace a cylinder wall that has been bored out to match this dimension, ensuring a proper fit and seal in modified B-Series blocks. The 12.5:1 compression ratio is a notable bump over stock, which will change the engine's power characteristics, typically resulting in more spirited acceleration when paired with appropriate tuning and supporting modifications.

Please note that this piston is not CARB approved and cannot be shipped to California. Always consult with your engine builder or a qualified mechanic to ensure this piston is the correct choice for your specific B-Series engine build and that all necessary supporting modifications and tuning are performed.
