Manley 93-97 Honda Del Sol / 99-00 Honda Civic SI (B16A1-A2-A3) 81mm STD Bore 9.8:1 Flat Top Piston

Manley Performance is known for building tough engine components that hold up under demanding conditions. If you're rebuilding the engine in your 1994-1997 Honda Civic del Sol or your 1999-2000 Civic SI, these forged pistons are a solid choice for getting more out of your B16A1, A2, or A3 engine. They're designed to handle increased stress and deliver reliable power.

These pistons are made from domestic 2618 alloy forgings, which are known for their strength. They feature cam and barrel skirt profiles that help them run smoothly against the cylinder walls, reducing wear while still making good power. The ring lands and grooves are machined to very precise standards, which is key for getting a good seal from your piston rings. This helps ensure that combustion pressure stays where it belongs, contributing to better engine performance and efficiency. Manley also uses a unique machining process that ensures the ring grooves are perfectly square to the piston skirt in one operation, which is important for proper ring function.

This set includes pistons with a standard 81mm bore and a 9.8:1 compression ratio, which is a common target for naturally aspirated or mild forced induction builds. They also come with chrome moly wrist pins, which are strong and durable. If you're looking to build a reliable performance engine, these pistons are a well-built option that many professional engine builders trust.
