Wiseco K673M82 Forged Piston Kit 82mm Bore -8cc Dish Honda Turbo

The Wiseco K673M82 is a high-performance forged piston kit engineered for turbocharged Honda engines. Featuring an 82mm bore diameter, a -8cc dished crown, and a 1.181-inch compression height, this piston is purpose-built to handle the increased cylinder pressures and thermal loads associated with forced induction applications.

The dished crown design lowers the effective compression ratio, making this piston an ideal foundation for turbocharged and supercharged builds where controlled compression is critical to reliability and power output. Wiseco's precision forging process produces a piston with the strength and dimensional consistency demanded by high-output performance engines.

Key Features:

• 82mm bore diameter for precise cylinder fit
• -8cc dished crown optimized for turbocharged and forced induction applications
• 1.181-inch compression height for accurate deck clearance
• Forged from high-silicon, low-expansion aluminum alloy for superior strength and heat transfer
• CNC-machined to tight tolerances for consistent performance and longevity
• Designed to withstand elevated cylinder pressures associated with turbocharging
• Includes high-performance piston rings, wrist pin, and circlips

Wiseco has been manufacturing forged pistons for over 80 years and is the only U.S.-based manufacturer of forged pistons for the performance and powersports markets. The K673M82 reflects that legacy of quality, delivering a race-proven component suitable for street performance builds, track use, and dedicated forced induction applications.
