Supertech Honda B20 Block B16 Head 84mm Bore +1.4cc Dome 11.5:1 CR Pistons - Set of 4 (Excl Rings)

If you're building a high-performance Honda engine using a B20 block with a B16 cylinder head, these Supertech pistons are a solid choice to consider. They're designed to work together, helping you achieve a specific compression ratio for improved power output. This set is for a 4-cylinder engine and includes four pistons, but remember they do not come with rings, so you'll need to source those separately.

These pistons are forged from high-strength aluminum, a common material for performance pistons because it can handle the heat and pressure of a modified engine while keeping weight down. They feature an 84mm bore, which is standard for many B20 blocks, and a +1.4cc dome shape. When paired with a B16 head, this combination is engineered to achieve an 11.5:1 compression ratio. This compression level is a popular choice for naturally aspirated builds aiming for a noticeable increase in horsepower and throttle response, offering a good balance between power and reliability for daily driving or track use.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always ensure you consult with your engine builder or a qualified mechanic to confirm these pistons are the right fit for your specific build and to get the correct ring set and other necessary components for installation. Proper installation and balancing are critical for engine longevity.
