$670.72

Supertech P4-VW18T83-N15ST-H13 Pistons

The Supertech P4-VW18T83-N15ST-H13 pistons are engineered for performance-driven applications, specifically designed for the Volkswagen 1.8T engine found in models from 1997 to 2000. Constructed from an advanced high-silicone 4032 alloy, these pistons offer low thermal expansion, exceptional wear resistance, and superior thermal conductivity, making them suitable for high-boost scenarios, including setups running up to 42psi with alcohol.

Manufacturing and Design

Utilizing a two or three-step forging process, these pistons exhibit a fine structural grain that enhances durability. The pistons undergo several machining processes using state-of-the-art CNC technology, ensuring precision and consistency in every unit. Heat treatments are applied to achieve high tensile strength and uniform hardness, critical for high-performance applications.

Key Features

  • Bore: 83mm
  • Compression Height: 29.5mm
  • Dome/Dish Volume: -15cc
  • Compression Ratio: 8.7:1
  • Set of 4 Pistons
  • Designed for Turbo/Nitrous Applications
  • Compatible with Ring Set GNH8300

Precision Engineering

Standard contact reduction grooves minimize friction, while the pin bores are honed and reamed for a precise fit. The wrist pins are made from cold-extruded chrome moly steel, ensuring high strength and reliability, secured with wire clip locks. To enhance performance further, a phosphate dry lubricant coating is applied, protecting the piston rings against micro-welding and improving lubrication in the skirt and cylinder area.

Fitment

  • Audi A4 1997-1999
  • Audi A4 Quattro 1997-2000
