Product Description

The Wiseco **K698M86** piston set is a high-performance, forged upgrade designed specifically for the Mitsubishi 4B11T engine used in the Lancer Evo X (2008-2015). Built from 2618 aluminum, these pistons deliver exceptional strength and durability, ideal for high-power and racing builds.

Featuring an 86.00 mm bore and a -8 cc dished profile, these pistons produce a lower compression ratio (~8.8:1), perfect for turbocharged applications that demand resistance to detonation. The ArmorGlide® coating on the skirts minimizes friction while the strutted forging reinforces key stress areas.

This piston kit includes everything needed for a complete rotating assembly upgrade: four pistons, wrist pins, circlips, and a performance ring set. Whether you're building a street monster or a track weapon, these pistons offer strength, reliability, and performance.
