These Mahle MS pistons are forged from 4032 aluminum, a material known for its strength and ability to handle higher temperatures and pressures compared to cast aluminum. This set is specifically designed for Honda B16 A1, A2, and A3 DOHC VTEC 1.6L engines, offering an 81.50mm bore size. The 9.1cc dish volume contributes to a 11.3:1 compression ratio, making them a solid choice for performance-oriented builds where improved power output is a goal.

Each piston measures 81.50mm in bore diameter with a 30mm compression height. They feature a 77.4mm stroke, a 134mm connecting rod length, and a 21mm wrist pin diameter. Weighing in at 312 grams each, these pistons are well-balanced for consistent engine operation. The 12.5:1 compression ratio is achieved with the 9cc dish, providing a significant boost over stock compression levels for enhanced engine performance.

This set includes four pistons, ready for installation in your B16 engine. Please note that these pistons are not CARB approved and cannot be shipped to California. They are also subject to California's Prop 65 warning.
