CP Piston & Ring Set for Acura B18C1 - Bore (81.5mm) - Compression Ratio (9.8)

CP Pistons is well-known for making strong internal engine components, and this piston and ring set is a prime example of their work for the 1994-2001 Acura Integra. If you're rebuilding the engine in your B18C1, this set is built to handle the demands of performance driving and racing applications. It's designed to be a direct replacement for your stock pistons, but with significant upgrades in strength and reliability.

This set features pistons with an 81.5mm bore, which is the standard size for a B18C1 engine, meaning you won't need to machine your cylinders if they are still within spec. The compression ratio comes in at 9.8:1, a solid figure that balances power output with the ability to run on pump gas in many setups. These are forged pistons, meaning they start as a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for higher-performance engines where increased cylinder pressures are common. The set includes the necessary rings, which are critical for sealing the combustion chamber and controlling oil consumption.

When installing these pistons, it's important to ensure your cylinder walls are clean and properly honed to the correct size, especially if you've had them bored out. Refer to the manufacturer's installation instructions for precise ring gap specifications and assembly procedures. Please note that this kit is not CARB approved and cannot be shipped to California.
