Manley 03-06 EVO VIII/IX 86.5mm Bore-+1.5mm Over Size-8.5/9.0 CR Dish Piston Set with Rings

If you're rebuilding the engine in your 2003-2006 Mitsubishi Lancer Evolution VIII or IX, or another compatible DSM vehicle like an Eagle Talon or Mitsubishi Eclipse, this Manley Performance forged piston set is a solid choice. These pistons are designed to replace your stock ones with a larger 86.5mm bore and a +1.5mm oversize, featuring a dish top that results in an 8.5 to 9.0 compression ratio. This setup is ideal for building a more powerful engine, whether you're aiming for street performance or track use.

Manley uses their signature 2618 alloy forgings, which are known for being strong and reliable under demanding conditions. They also come with premium chrome moly wrist pins, and the piston skirts have proven cam and barrel profiles. These profiles help the pistons move smoothly against the cylinder walls, reducing wear and contributing to power gains. Manley also pays close attention to the ring lands and grooves, ensuring a tight seal with your piston rings for better compression and less blow-by. The machining process is unique, allowing them to turn the skirt and cut the ring grooves in one operation, which helps maintain squareness between the skirt and the grooves for optimal ring seal.

This set includes the pistons, rings, and wrist pins, making it a comprehensive package for your engine build. It's important to note that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
