CP Piston & Ring Set for Acura B18C1 - Bore (82.0mm) - Size (+1.0mm) - CR (12.5) SINGLE PISTON

Forged from 2618 aluminum alloy, this CP Pistons single piston is built for performance applications. It's designed for the Acura B18C1 engine, featuring an 82.0mm bore and a +1.0mm oversize dimension, meaning it's intended to replace a worn or slightly damaged cylinder with a fresh, larger bore size. The 12.5:1 compression ratio is notably higher than stock, which can increase power output when paired with appropriate tuning and fuel. This piston is sold individually, so you'll need to order the correct quantity for your engine.

The 2618 aluminum alloy is chosen for its strength and ability to withstand high temperatures and pressures, making it a solid choice for builds that see regular track use or aggressive street driving. The included rings are designed to seal effectively against the cylinder wall, ensuring good compression and oil control. Because this is an oversize piston, it's important to ensure your engine block has been properly machined to the correct 82.0mm bore size before installation.

Please note that this piston set is not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified mechanic to confirm compatibility with your specific engine build and tuning strategy.
