Supertech Honda B16 81.5mm Bore 5.7cc Dome 10.5:1 CR/11.9:1 CR Pistons - Set of 4 (Excl Rings)

If you're rebuilding the engine in your Honda B16, these Supertech forged pistons are a solid option for boosting performance. This set includes four pistons, each with an 81.5mm bore and a 5.7cc dome. They're designed to achieve a compression ratio of either 10.5:1 or 11.9:1, depending on your cylinder head setup. This means you can tailor the engine's compression to match your specific build goals, whether you're aiming for naturally aspirated power or forced induction.

Supertech uses a forged aluminum construction for these pistons, which is much stronger and more durable than cast aluminum. This makes them ideal for high-performance applications where increased cylinder pressures are common. The dome shape is carefully designed to promote efficient combustion and can help reduce detonation. It's important to note that this set does not include piston rings, so you'll need to purchase those separately to complete the installation. These pistons are not CARB approved and cannot be shipped to California.
