If you're rebuilding the engine in your Subaru EJ20 or EJ207, a solid set of pistons is crucial for performance and reliability. This Mahle MS Piston Set is built for those demanding builds, offering a 92.50mm bore size and a 75.0mm stroke, designed to work with a 130.4mm rod. The -12cc dish volume contributes to an 8.0:1 compression ratio, making these pistons a good choice for boosted applications where you need to control detonation.

Mahle uses a 4032 aluminum alloy for these pistons, which is known for its strength and resistance to expansion at higher temperatures. This material choice helps ensure durability under stress. Each piston weighs in at 352g, and they come with a 23mm wrist pin. This set includes four pistons, ready to be installed in your EJ20 or EJ207 engine. Remember, these are not CARB approved and cannot be shipped to California.
