What is the compression ratio with these pistons?

These pistons have a -10.0cc dish volume, which results in an approximate compression ratio of 9.0:1 when used with the specified stroke and rod length. This is a common target for modified engines.

What material are these pistons made from?

The pistons are forged from 2618 aluminum. This material is chosen for its strength and ability to handle high temperatures and pressures found in performance engine applications.

Are these pistons suitable for all 4G63 engines?

This set is specifically designed for the 4G63 2.0L engine found in Mitsubishi vehicles from 1993 to 2009. Always confirm your specific engine code and year range before purchasing.

Product Details

If you're rebuilding the engine in your 1993-2009 Mitsubishi 4G63 2.0L, this Mahle MS Piston Set is a solid option. Mahle is a well-known name in engine components, and these pistons are built for performance and durability. They feature an 86.00mm bore and are designed to work with an 88.0mm stroke and a 150mm rod, utilizing a 22mm wrist pin. The -10.0cc dish volume contributes to a 9.0:1 compression ratio, which is a common target for modified 4G63 engines looking for a balance between power and pump gas usability.

These pistons are forged from 2618 aluminum, a strong material commonly used for high-performance pistons because of its excellent strength-to-weight ratio and ability to withstand high temperatures and pressures. Each piston weighs in at 321g, helping to keep reciprocating mass manageable for improved engine response. The 150mm rod length and 22mm pin diameter are standard for many 4G63 applications, ensuring a good fit with many aftermarket and stock connecting rods. This set includes four pistons, ready for your engine build.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures when working on your engine.
