Supertech Honda B16 81.5mm Bore 7.5cc Dome 11:1 CR Pistons - Set of 4 (Excl Rings)

Supertech is known for making well-built engine components, and these forged pistons for the Honda B16 are a prime example. If you're rebuilding the top end of your B16 engine and looking for a solid upgrade, these pistons are designed to handle increased performance demands. They feature an 81.5mm bore, a 7.5cc dome volume, and are designed to achieve an 11:1 compression ratio, which is a notable bump from stock and can help improve power output when paired with appropriate tuning.

These pistons are forged from high-strength aluminum alloy, a common choice for performance applications because it offers a good balance of strength and weight. Forging is a manufacturing process that shapes metal under extreme pressure, resulting in a denser, stronger grain structure compared to cast pistons. This makes them more resistant to the stresses and heat generated in a performance engine. The 7.5cc dome shape is specifically designed to work with the B16 cylinder head to achieve that 11:1 compression ratio, which is a popular target for naturally aspirated builds seeking improved throttle response and overall power.

This set includes four pistons, but remember that piston rings are sold separately, so you'll need to factor that into your build. It's also important to note that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and reliability, ensure these are installed by a qualified mechanic who can properly balance the rotating assembly and set up the engine management system to take advantage of the new compression ratio.
