Product Description

The Wiseco K614M83 is a high-performance, forged-piston kit tailored for the Mazda 2.0 L FS engine - commonly found in 1993-2002 Mazda 626, 1993-1997 Ford Probe, and the turbocharged 2003 Mazdaspeed Protege. Built from 2618 aluminum, these pistons are strong and durable for street, track, or boosted applications.

Each piston features a dished crown (-16.5 cc) to maintain a safe compression ratio, while the strutted forging enhances structural rigidity under load. The ArmorGlide® coating on the skirts reduces friction and wear, and forced pin-oiling ensures consistent lubrication even during high-RPM or high-boost operation.

This kit includes a performance ring set and is designed for serious engine builds - whether you're doing a turbo upgrade or a high-revving naturally aspirated setup. Proper installation (checking ring gaps, clearances, and torque) is recommended for maximum durability and performance.
