Supertech Performance P4-VW16-ABF-82.5 Forged Piston Bore - 82.5mm

The Supertech Performance P4-VW16-ABF-82.5 is a high-performance forged piston designed for naturally aspirated and nitrous oxide applications in VW 16-valve ABF engines. This precision-engineered piston features an 82.5mm bore diameter and is sold individually, allowing you to order exactly what you need for your engine build.

Advanced Alloy Construction:

Manufactured from extruded 4032 aluminum alloy enhanced with additional copper, nickel, and magnesium, these pistons offer low thermal expansion, excellent wear resistance, and superior thermal conductivity. This proven alloy formulation has successfully withstood boost pressures up to 42 psi when used with alcohol fuel.

Key Features:

• Two or three-step forging process creates fine structural grain for maximum strength
• Precision CNC machined to exacting tolerances
• Multiple heat treatments provide high tensile strength and uniform hardness
• Contact reduction grooves machined as standard
• Honed and reamed pin bores for precise wrist pin fit
• Cold extruded chrome moly steel wrist pins with wire clip locks included
• Phosphate dry lubricant coating protects rings and enhances skirt lubrication
• Compatible with ring set 895052-00

Important Notes:

Compression ratios are calculated using a 0.030" head gasket and 0.010" deck height unless otherwise specified. Each piston is sold separately—for a complete 4-cylinder engine, order quantity of 4.
