The Manley 606215CE-4 is a Platinum Series Extreme Duty forged piston set engineered for the Mitsubishi 4G63 2.0L engine platform.

Key Features:

• 2618 Alloy Forging: Domestic 2618 high-strength alloy construction delivers superior tensile strength and thermal fatigue resistance under extreme operating conditions
• Flat Top / -2.5cc Crown: Optimized crown geometry for precise compression ratio tuning in turbocharged 4G63 builds
• Extreme Duty (CE) Construction: Platinum Series designation with enhanced durability features for high-horsepower and boosted applications
• Chrome Moly Wrist Pins: Premium .150" wall x 2.250" length Chrome Moly pins included for strength and reliability
• Offset Wrist Pin Design: Reduces piston rock and noise during cold starts
• Pressure Balance Groove: Improves ring seal and reduces blow-by for greater power retention
• Cam and Barrel Skirt Profile: Proven skirt geometry maximizes power output while minimizing cylinder wall wear
• Exacting Ring Lands and Grooves: Precision-machined to strict tolerances for enhanced ring seal and consistent power
• Single-Operation Machining: Unique fixturing ensures perfect ring groove-to-skirt squareness for superior seal geometry
• Steel Top Ring Sets and Round Wire Locks Included

Recommended piston-to-wall clearance is .0035", measured 1.100" from the bottom of the oil ring groove. This set is the go-to choice for engine builders and tuners constructing serious street, track, or time-attack 4G63-based powerplants requiring a reliable forged piston solution at an overbore specification.
