Product Description

The Wiseco K544M87 piston kit is designed for serious performance builds using Honda H-series engines, specifically the H22 (2.2 L) and H23 (2.3 L) found in Prelude and Accord models. Built from high-strength 2618 alloy, these forged pistons deliver excellent durability and resilience, even under high-stress or high-RPM conditions.

With a -14 cc dish in the crown, this design optimizes compression: around ~8.4:1 for H22 and up to ~9.2:1 for H23 variants. That makes the kit versatile for both NA and moderately tuned engines. The ArmorGlide skirt coating minimizes friction and noise, while precise ring grooves and a high-quality ring set help maintain reliable sealing and reduce blow-by.

The supplied 22 mm wrist pins (with forced oiling) and strutted forging lend stability and low wear, making this kit well-suited for VTEC or high-rev street builds. For engines with FRM (fiber-reinforced metal) cylinders, sleeving is required; otherwise, you get a race-grade, highly reliable piston set built for performance and longevity.
