CP Piston & Ring Set for Honda L15B7/L15B8 - Bore 73.5mm - Size (+.50) - Compression Ratio 10.5

Forged from high-strength aluminum alloy, this CP Pistons set is built for demanding engine builds. The pistons measure 73.5mm in bore diameter and are sized at +.50mm, meaning they are intended for an engine block that has been bored out to accommodate this larger size. This specific set is designed to achieve a 10.5:1 compression ratio, a notable increase over stock that can significantly improve power output when paired with appropriate tuning and supporting modifications.

CP Pistons are well-known for their robust construction, utilizing advanced forging techniques to create pistons that are both lightweight and incredibly strong. This strength is crucial for handling the increased cylinder pressures and temperatures common in performance applications. The included rings are designed to seal effectively against the cylinder walls, ensuring optimal compression and efficient oil control, which is vital for engine longevity and performance. This set is a solid option for anyone rebuilding or modifying their Honda L15B7 or L15B8 engine and looking for reliable, high-performance internal components.

When installing this set, remember that the +.50mm sizing indicates your engine block will need to be machined to this specific bore size. Proper balancing of the rotating assembly is also recommended for smooth operation and to reduce stress on other engine components. This piston set is intended for off-road use or competition vehicles and is not CARB approved, meaning it cannot be legally shipped to California.
