What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide skirt coating on these Wiseco pistons is designed to reduce friction between the piston skirt and cylinder wall. This helps prevent seizing and can also contribute to quieter operation of the engine.

What does the -17cc dish mean for my engine build?

The -17cc dish is a feature on the piston crown that helps to lower the compression ratio. This is often necessary when building a turbocharged or supercharged engine to prevent detonation and allow for safe boost levels.

Are these pistons compatible with all Mitsubishi 4G63 engines?

This piston set is specifically designed for the 4G63 engine found in various Mitsubishi, Eagle, and Plymouth models from the mid-90s to the mid-2000s. Always verify your specific vehicle's engine code and year range against the fitment data to ensure compatibility.

Product Details

When you're building a serious performance engine, especially for turbocharged Mitsubishi applications like the 4G63, you need pistons that can handle the stress. This kit from Wiseco gives you a full set of four forged pistons, each measuring 87mm in bore diameter. They're designed with a -17cc dish to help achieve your desired compression ratio, and feature precision ring grooves for improved sealing. You'll also find anti-detonation grooves and other features aimed at keeping things sealed tight under high pressure.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its strength under high temperatures and loads. Wiseco also applies their ArmorGlide skirt coating, which is designed to reduce friction, resist seizing, and even quiet down operation. The fully machined crown and forced pin oiling are details that show these are built for demanding use, whether it's for heavy-duty street performance or full-on racing builds. This set is intended for sport compact applications and fits a range of vehicles including the Mitsubishi Eclipse, Lancer, and Eagle Talon.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. Make sure to check the manufacturer's installation instructions for proper setup, as precise assembly is key for these high-performance components.
