CP Piston & Ring Set For Arias Honda 2.4L K Series - Bore 3.445 - Size (+0.5mm) - CR (11.1:1)

Forged from high-strength aluminum alloy, these CP Pistons are built to handle the demands of a performance Honda 2.4L K Series engine. The 3.445-inch bore size, combined with a 0.5mm oversize, is designed for engines that have been bored out to accommodate larger pistons, often during a rebuild or performance upgrade. This specific set is engineered for an 11.1:1 compression ratio, which is a notable increase over stock, meaning you'll get more power out of every combustion cycle. CP Pistons are well-known for their robust construction, making them a solid choice for builders looking for reliable performance under stress.

These pistons feature a specific dish design that contributes to the 11.1:1 compression ratio when paired with the correct cylinder head and gasket combination. The included rings are also selected to work in harmony with the piston design, ensuring proper sealing for optimal power and efficiency. Because these are forged pistons, they offer significantly improved strength and durability compared to cast pistons, which is crucial for engines that see hard use or are modified for higher horsepower output. The 0.5mm oversize is important to note; this set is intended for engines that have already been machined to this larger bore size.

When installing these pistons, it's essential to follow the manufacturer's recommended clearances and lubrication procedures to ensure longevity and performance. Given the performance nature of these components, they are typically part of a larger engine build that may include upgraded camshafts, cylinder heads, and a robust engine management system to take full advantage of the increased compression and airflow. Please be aware that this part is not CARB approved and cannot be shipped to California.
