What is the purpose of the -11cc dome on these pistons?

The -11cc dome is a specific volume that affects the engine's compression ratio when paired with a particular cylinder head. This design is intended for performance builds where a specific compression ratio is targeted for increased power output.

Are the piston rings and connecting rods included with this set?

No, this set includes only the pistons and wrist pins. You will need to source compatible piston rings and connecting rods separately to complete your engine build.

What makes these pistons 'Extreme Duty'?

The 'Extreme Duty' designation comes from the use of strong 2618 alloy forgings and robust tool steel wrist pins. These materials and construction methods allow the pistons to withstand higher cylinder pressures and temperatures common in performance or racing applications.

About this part

Product Details

If you're rebuilding the engine in your 2008-2015 Mitsubishi Lancer Evolution, especially for high-performance applications, a strong set of pistons is crucial. These Extreme Duty pistons from Manley are built to handle the demands of serious engine work, offering a solid foundation for your build. They feature an 86.5mm bore and a -11cc dome, designed to work with specific compression ratios and cylinder head configurations.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to withstand high temperatures and pressures. The pistons also come with tool steel wrist pins for added durability, and feature cam and barrel skirt profiles. These profiles are carefully shaped to help the piston move smoothly in the cylinder, reducing wear on the cylinder walls while still allowing the engine to make good power. The ring lands and grooves are machined to exacting standards, which is important for getting a good seal with your piston rings, ultimately leading to better compression and more power.

These pistons are a popular choice among professional engine builders and tuners who need reliable components for performance engines. They are designed to be a direct replacement for your stock pistons, assuming your engine build requires this specific bore size and dome volume. Keep in mind that these are not CARB approved and cannot be shipped to California. For a complete engine build, you'll want to ensure you have all the necessary supporting components, such as rings, connecting rods, and bearings, which are typically sold separately.
