CP Piston & Ring Set for Honda D16A6 - Bore (75.5mm) - 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 D16A6 engine. The 75.5mm bore size, which is 0.5mm larger than stock, is ideal for rebuilding an engine that has been previously bored or for those looking to slightly increase displacement. This specific set is designed to achieve a 9.0:1 compression ratio, a solid choice for naturally aspirated builds or those running moderate boost levels where reliability is key.

CP Pistons are well-known in the performance community for their robust construction and precise manufacturing. Each piston in this set is forged, meaning the aluminum is heated and shaped under extreme pressure, creating a denser, stronger grain structure compared to cast pistons. This makes them significantly more resistant to detonation and fatigue, which is crucial when you're pushing an engine beyond its original specifications. The included rings are matched to the pistons for a proper seal, helping to maintain compression and control oil consumption.

This piston and ring set is a direct fit for the 1986-1989 Acura Integra, as well as 1988-1991 Honda CRX and 1990-1991 Honda Civic models equipped with the D16A6 engine. When rebuilding your engine, ensure you consult the manufacturer's installation instructions for proper piston ring gap, lubrication, and torque specifications to ensure optimal performance and longevity. Please note that this part is not CARB approved and cannot be shipped to California.
