Wiseco Pistons K676M87AP Forged Piston Kit Bore Compression - 4G63 7-Bolt 87mm 10.5 1

The Wiseco K676M87AP forged piston kit is engineered specifically for Mitsubishi 4G63 7-bolt engines, delivering high-performance reliability for turbocharged and naturally aspirated applications. This complete piston set features an 87mm bore diameter with a 1.9cc dome design that produces a 10.5:1 compression ratio, ideal for street performance and aggressive tuning.

Key Features:

• Forged from aerospace-quality 2618 aluminum alloy for maximum strength and durability
• 87mm bore diameter with 1.9cc dome configuration
• 10.5:1 compression ratio optimized for forced induction and high-performance applications
• Designed specifically for Mitsubishi 4G63 7-bolt engine blocks
• ArmorGlide skirt coating reduces friction and wear during break-in and operation
• Precision machined ring grooves for optimal seal and reduced blow-by
• Includes pistons, rings, wrist pins, and circlips for complete installation

Wiseco pistons are manufactured in the USA using advanced forging techniques and CNC machining to deliver precise tolerances and consistent quality. The domed piston crown design promotes efficient combustion while maintaining detonation resistance, making this kit suitable for both street and competition use in popular platforms like the Mitsubishi Eclipse, Eagle Talon, and Galant VR-4.
