Supertech BMW B58 82mm Bore 36cc 11:1 CR Pistons - Set of 6 (Excl Rings)

P4-MINB48-82-CR11-6

Supertech Forged Piston Kit for Toyota B58B30 – 82mm +STD

Supertech Pistons are manufactured from extruded high-silicone, enhanced 4032 alloy (with additional Cu, Ni, and Mg) that has low thermal expansion, excellent wear resistance, and higher thermal conductivity. This makes them ideal for high-performance street and racing environments where strength, temperature stability, and long service life are critical.

Each piston is engineered for precision and performance, featuring a lightweight 298g design, +STD overbore, and a slipper design skirt profile to reduce friction and optimize combustion. Perfect for builders and enthusiasts requiring consistent power delivery and long-lasting reliability across a range of engine configurations.

Features

• Forged from extruded high-silicone, enhanced 4032 alloy (with additional Cu, Ni, and Mg) that offers low thermal expansion and excellent wear resistance
• Precision CNC-machined and multi-stage heat treated for grain uniformity
• Phosphate dry-lubricant coating on ring grooves and piston skirt
• +STD oversize bore for expanded displacement and tuning flexibility
• 298g piston weight optimized for quick acceleration and reduced stress
• slipper design skirt style enhances piston stability and reduces drag

Benefits

• Excellent wear resistance and higher thermal conductivity
• Superior dimensional stability under extreme loads and heat
• Reduced piston-to-wall clearance for quieter operation and better sealing
• Reliable for naturally aspirated, turbocharged, or nitrous-assisted setups
