The 81.0mm bore size is specific to certain B18C1 engine builds, and the 9.8:1 compression ratio is a popular target for naturally aspirated or mild forced induction setups, offering a good balance between power and reliability. This piston is sold individually, so you'll need to order the correct quantity for your engine.
