Manley 03-06 Mitsubishi Evo 8/9 4G63T 86.5mm +1.5mm -8cc Dome 94mm Stroke Pistons w/ Rings

Manley Performance is well-known for building strong engine components, and their Platinum Series pistons are a popular choice among professional engine builders and tuners. If you're working on a 2003-2006 Mitsubishi Evo 8 or 9 with the 4G63T engine, these pistons are designed to handle the demands of a performance build. They feature a bore size of 86.5mm, a dome volume of -8cc, and are intended for a 94mm stroke, which is a common setup for these cars when increasing displacement.

These pistons are forged from domestic 2618 alloy, a material chosen for its superior strength and performance under high stress. They also come with premium chrome moly wrist pins, known for their durability. Manley pays close attention to the details, ensuring exacting standards for the ring lands and grooves. This precise machining helps achieve a better ring seal, which translates directly into more power. The pistons also feature cam and barrel skirt profiles that are designed to generate significant power while minimizing wear on the cylinder walls. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation, ensuring the ring groove is perfectly square to the skirt for optimal performance.

This set includes the pistons and rings, ready for installation. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance 4G63T engine, these Manley pistons offer a well-built foundation for your project.
