Manley Hyundai Genesis Coupe 2.0L Turbo 86.0mm +.5mm Oversized Bore 9.3:1 Dish Piston Set with Rings

If you're rebuilding the engine in your 2010-2013 Hyundai Genesis Coupe 2.0L Turbo, a solid set of pistons is crucial for getting back on the road with confidence. This set from Manley Performance is built to handle the demands of a performance engine, whether you're restoring it to stock or aiming for more power.

These pistons are forged from 2618 alloy, a strong material chosen for its ability to withstand high temperatures and pressures common in turbocharged engines. They feature a dish design with a 9.3:1 compression ratio and are precisely machined to an 86.0mm bore, which is +.5mm oversized from the factory specification, making them ideal for engine rebuilds where cylinder walls may need honing to a larger size. Manley also uses proven cam and barrel skirt profiles, which help reduce friction and wear on the cylinder walls, contributing to both performance and longevity. The set includes tool steel wrist pins and moly skirt coatings on select parts, further enhancing durability.

Manley's attention to detail extends to the ring lands and grooves, which are machined to exacting standards to ensure a tight seal with the piston rings. This precise fitment is key to maximizing compression and preventing blow-by, ultimately leading to more power and better engine efficiency. The unique fixturing Manley uses allows them to machine the skirt and ring grooves in one operation, ensuring the squareness between the piston skirt and the ring grooves, a critical detail for proper ring function.
