The Wiseco K682M875AP is a Professional Series forged racing piston kit designed for serious Honda S2000 F22C engine builders and racers. Wiseco forged pistons are manufactured from certified aluminum alloys through a controlled forging process that aligns the metal's grain structure for superior strength and durability.

Key Features:

• Engineered, forged, and machined in the USA from 2618 aluminum for improved tensile strength
• Anti-friction skirt coating helps minimize scuffing during break-in and lower friction on the cylinder wall
• Armor Plating coating raises hardness of aluminum, increases ring groove durability, prevents micro-welding of piston rings, and reduces carbon buildup
• Textured top face improves combustion characteristics
• Specially designed valve pockets, optimized skirt profiles, and steel nitride/napier rings
• Complete kit includes premium 4130 chrome moly wrist pins and gas nitrided piston ring set

Compatible with 90.75mm stroke and 149.65mm connecting rods, with 23mm (0.905") pin diameter. Note: FRM cylinders must run sleeved bores with these pistons. Forged from 2618 alloy and designed for use with forced induction and nitrous applications.
