Manley 03-06 Evo 8/9 4G63T 85.5mm+.5mm Oversized Bore 8.5/9.0:1 Dish Single Piston w/ Rings

If you're rebuilding the engine in your 1993-1999 Mitsubishi Eclipse, Eagle Talon, Plymouth Laser, or 2003-2006 Mitsubishi Lancer, a strong set of pistons is crucial. This single piston from Manley Performance is designed for the 4G63T engine, featuring an 85.5mm bore that's 0.5mm oversized. It's built with a dish design that results in a compression ratio of 8.5:1 or 9.0:1, depending on your cylinder head volume.

Manley uses 2618 alloy forgings for these pistons, which are known for their strength and ability to handle demanding engine conditions. They also come with tool steel wrist pins and have precisely machined ring lands and grooves to ensure a good seal. The cam and barrel skirt profiles are shaped to help the piston move smoothly against the cylinder wall, reducing wear and contributing to power output. This attention to detail in machining helps ensure the piston rings seal well, which is key for making good power and maintaining engine health.

This piston is sold individually, so you'll need to order the correct quantity for your engine build. Remember that this part is not CARB approved and cannot be shipped to California.
