Manley 97-00 Honda CRV (B20B4 w/ B16A1-A20A3) 84.5mm Bore +.5mm Oversize 12.5:1 Dome Piston - Single

Starting with a 2618 alloy forging, these Manley pistons are built for serious work under the hood. They're designed for the 1994-2001 Acura Integra, specifically for the B20B4 engine with B16A1-A20A3 components, and come in an 84.5mm bore size that's +.5mm oversize. This means they're intended for a freshly bored or honed cylinder block, ensuring a solid fit and optimal compression.

The dome shape on this piston is designed to achieve a 12.5:1 compression ratio, which is a notable bump over stock. This higher compression helps extract more power from your fuel, especially when paired with an engine tune. Manley uses proven cam and barrel skirt profiles that help reduce friction and wear on your cylinder walls, even with the increased performance. They also pay close attention to the ring lands and grooves, machining them to strict standards for a better seal and more consistent power delivery.

Each piston comes with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt. This level of detail matters for engine longevity and performance. Keep in mind these are not CARB approved and cannot be shipped to California.
