Wiseco Mitsubishi EVO X 4B11 Turbo -8cc 86.75mm Bore 8.8 CR HD Forged Piston Kit

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance builds. The -8cc dish volume contributes to the 8.8:1 compression ratio, making them a solid choice for turbocharged 4B11 engines where controlled combustion is key. Each piston is machined in the USA, ensuring precision in every detail.

Wiseco's Professional Series pistons are packed with features for durability and performance. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal under high stress. The ArmorGlide skirt coating helps reduce friction and noise, while also resisting seizure. The fully machined crown and forced pin oiling further contribute to their ability to handle severe duty applications. This kit includes four pistons, ready for your engine build.

When rebuilding a high-performance 4B11 engine, especially for racing, these pistons are designed to remove your limits. Remember that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
