Wiseco K671M8950AP ArmorPlated Piston Kit 89.50mm Bore

The Wiseco K671M8950AP is an ArmorPlated (AP) forged piston kit precision-engineered for high-performance and racing applications. Featuring an 89.50mm bore diameter, this piston is manufactured from aerospace-quality 2618 aluminum alloy forging for superior strength and durability under extreme heat and pressure.

Wiseco's ArmorPlated technology applies a hard-anodized coating to the piston skirt, dramatically reducing friction and wear while improving scuff resistance during cold starts and high-RPM operation. This coating also enhances thermal management, helping the piston maintain tight tolerances over a longer service life compared to uncoated alternatives.

Key Features:

• Bore Size: 89.50mm
• ArmorPlated (AP) skirt coating for reduced friction and extended wear life
• Forged 2618 aluminum alloy construction for high-strength, lightweight performance
• CNC-machined to tight tolerances for optimal ring seal and combustion efficiency
• Includes piston, wrist pin, clips, and rings (full kit)
• Designed for performance street, track, and racing applications
• Drop-in fitment for supported engine applications

Wiseco pistons are manufactured in the USA and are a trusted choice among professional engine builders and performance enthusiasts. The K671M8950AP delivers the reliability and performance needed for demanding builds where stock pistons fall short.
