Mahle MS Piston Set EJ20/207 92.50mm Bore 79.0mm Stroke 130.4mm Rod 23mm Pin -16cc 8.0 CR Set of 4

Mahle is well-known for its extensive range of high-performance engine components, and this Mahle MS Piston Set is a prime example of their commitment to quality for demanding builds. This set is specifically designed for EJ20 and EJ207 engines, offering a 92.50mm bore and a 79.0mm stroke, which are critical dimensions for engine performance and reliability. The pistons are crafted from 4032 aluminum, a material chosen for its strength and ability to handle higher temperatures and pressures often found in modified or performance-oriented engines. Each piston weighs 337g and features a -16.0cc dish volume, contributing to an 8.2:1 compression ratio, a common target for builds seeking improved power without sacrificing too much drivability.

The design includes a 130.4mm rod length compatibility and a 23mm wrist pin diameter, ensuring proper fitment with many performance connecting rods. These pistons are built to withstand the stresses of increased horsepower and torque, making them a solid choice for engine rebuilds where durability and performance are paramount. The 4032 aluminum construction offers good thermal expansion properties, which helps maintain proper piston-to-wall clearance across a wider operating temperature range. This attention to material science and precise manufacturing means you're getting a well-built component that can contribute to the longevity and performance of your engine.

When undertaking an engine build with these pistons, it's important to note that they are not CARB approved and cannot be shipped to California. This is a common consideration for performance parts that may not meet specific emissions standards. Ensure you have the correct connecting rods and other necessary engine components to match the specifications of this piston set for a successful installation. This set includes four pistons, ready for your next engine project.
