Supertech Honda B16 82mm Bore 5.9cc Dome 10.5:1 CR Pistons - Set of 4 (Excl Rings)

If you're rebuilding the engine in your Honda B16, these Supertech pistons are a solid option for achieving a 10.5:1 compression ratio. This set includes four pistons, each with an 82mm bore and a 5.9cc dome volume, designed to work with your B16 engine. They are forged from high-strength aluminum, which makes them well-built for the demands of performance applications.

Forged pistons are a step up from cast pistons because they undergo a process that aligns the metal's grain structure, making them significantly stronger and more resistant to detonation and fatigue. This strength is crucial when you're increasing compression or planning to tune your engine for more power. The 82mm bore size is a common upgrade for B16 engines, allowing for a slight increase in displacement over the stock bore. Remember that this set does not include piston rings, so you'll need to source those separately to complete the installation.

When installing these pistons, it's important to follow the manufacturer's specifications for piston-to-wall clearance and ring gap. Proper installation is key to ensuring the longevity and performance of your engine rebuild. These pistons are intended for off-road use and are not CARB approved, meaning they cannot be shipped to California.
