What is the compression ratio with these pistons?

These pistons feature a -35cc dish volume, which results in an 11.4:1 compression ratio when used with appropriate cylinder heads and deck height. This is a common target for performance builds seeking increased power.

Are these pistons suitable for a daily driver?

These are forged pistons designed for high-performance applications. While they offer superior strength, they are typically used in modified engines where increased cylinder pressures are expected. For standard street use, cast pistons might be more common, but these offer enhanced durability for demanding builds.

What does 'Not CARB approved' mean?

This means the pistons do not meet the emissions standards set by the California Air Resources Board (CARB). As a result, they cannot be legally shipped to or installed on vehicles registered in California.

Product Details

Mahle is a well-known name in engine components, trusted for their precision and reliability. This Mahle MS Piston Set is built for performance applications, specifically designed for 3.8L engines. If you're rebuilding the heart of your engine and looking for robust components that can handle increased stress, this set is a solid option.

This set features pistons with a 102.0mm bore and a 35cc dish, contributing to an 11.4:1 compression ratio. The 80.4mm stroke and 127mm rod length are key dimensions for engine builders to consider when matching components for optimal performance. Each piston pin measures 22mm, a common size for performance builds. These pistons are forged, meaning they start as a solid block of aluminum that is heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for high-performance engines where increased cylinder pressures are common.

This set includes six pistons, enough for a complete six-cylinder engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine build specifications and manufacturer's instructions to ensure proper installation and compatibility with your specific engine components.
