Mahle MS Subaru EJ20 93.00mm Bore 79.0mm Stroke 130.5mm Rod 23mm Pin -16cc 8.3 CR - Piston Set of 4

Forged from 2618 aluminum alloy, these Mahle MS pistons are built for performance applications in Subaru EJ20 engines. The -16cc dish volume contributes to an 8.3:1 compression ratio, making them suitable for boosted setups where controlled compression is key. Each piston weighs in at 354g, a testament to their robust construction without unnecessary bulk.

With a 93.00mm bore and a 79.0mm stroke, these pistons are designed to work with a 130.5mm connecting rod and feature a 23mm wrist pin. The 30.3mm compression height ensures proper piston-to-valve clearance and deck height when paired with the correct connecting rod and crankshaft combination. Mahle's reputation for well-built engine components means you're getting a part designed for durability and performance under demanding conditions.

This set includes four pistons, ready for your engine rebuild. Please note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or a professional mechanic for specific installation requirements and compatibility with your build.
