Product Description

The Wiseco K570M92 piston kit is built for high-performance and turbocharged Mitsubishi 6G72 engines - notably used in the 3000GT and similar V6 turbo platforms. These forged pistons feature a -14 cc dish crown to reduce static compression, making them ideal for forced-induction or heavily tuned builds.

Forged from durable 2618 aluminum, the pistons can handle high stress and high RPM operation. Their ArmorGlide-coated skirts reduce friction and improve durability, while the strutted forging design enhances structural rigidity. The kit includes a matched ring set (9200XX) and 22 mm wrist pins for reliable, high-performance sealing and connection.

When installing, it's important to check bore-to-wall clearance, ring gap, and deck height to ensure optimal performance and longevity. Given the dished design, selecting an appropriate head gasket and verifying resulting compression ratio is critical for building a reliable, powerful engine.
