CP Piston & Ring Set for Acura B18C1 - Bore (82.0mm) - Size (+1.0mm) - Compression Ratio (12.5)

This is a set of forged pistons and rings from CP Pistons, specifically made for the 1994-2001 Acura Integra with the B18C1 engine. These pistons are designed to replace your stock ones when rebuilding or upgrading your engine. They come at a +1.0mm oversize, meaning the bore diameter is 82.0mm, which is 1.0mm larger than the factory specification. This is often done to correct wear in the cylinder walls or to increase displacement for more power.

CP Pistons are well-known for their robust construction, and this set is no different. Forged from high-strength aluminum alloy, these pistons are built to handle the increased stresses of a performance engine. The included rings are also designed to seal effectively against the cylinder walls, ensuring good compression and oil control. With a compression ratio of 12.5:1, these pistons will raise the compression of your B18C1 engine, which generally leads to improved throttle response and more power, especially when paired with appropriate tuning. This set includes the pistons and the necessary rings to get your engine back together.

When installing these pistons, it's important to ensure your engine block has been properly machined to the correct bore size and finish. Because these are an oversize part, the cylinders will need to be bored and honed to 82.0mm. Always refer to the manufacturer's installation instructions for specific details regarding ring gap, piston-to-wall clearance, and assembly procedures. Please note that this part is not CARB approved and cannot be shipped to California.
