Wiseco K741M82 Forged Piston Kit for BMW B58 and Toyota Supra

The Wiseco K741M82 is a high-strength forged piston kit specifically engineered for BMW B58 engines and the Toyota Supra B58, addressing the pistons as a potential point of failure when adding power to these turbocharged inline-six engines. These pistons are forged from aerospace-grade aluminum for ultimate quality and strength, making them ideal for high-performance builds and forced induction applications that exceed stock engine capabilities.

Key Specifications:

• 94.6mm bore size with 33.30mm compression height
• ArmorGlide skirt coating for reduced friction and quieter operation
• Dry film lubricant coating that reduces friction, improves performance, and quiets piston operation
• Complete kit includes pistons, rings, wrist pins, and circlips

Application:

This piston set is designed for 2015-2023 BMW vehicles equipped with the B58 3.0L turbocharged inline-six engine, as well as 2020-2022 Toyota Supra models. The forged construction is crucial for high-performance race applications, where increases in horsepower and compression stress components far beyond stock engine limits.

Wiseco's precision engineering ensures proper fitment and reliability for builds ranging from street performance to track-focused applications. Each piston is manufactured in the USA using state-of-the-art forging and CNC machining for consistent quality and tight tolerances.
