CP Pistons are well-known for their strong construction, and these forged pistons are built to handle the demands of performance applications. The forging process creates a denser, stronger material compared to cast pistons, which can be beneficial if you're pushing your engine beyond stock power levels. The 9.0:1 compression ratio is a common target for naturally aspirated builds or those using moderate boost, offering a good balance between power and drivability.

When rebuilding your B18, ensuring you have reliable internal components is key. These pistons are a popular option for enthusiasts looking for a durable replacement or a foundation for a more powerful engine build. Remember that this part cannot be shipped to California due to emissions regulations.
