Supertech Honda B18 82mm 1.181in CH -2.5cc Flat Top Piston - Set of 4 (Excl Rings)

Supertech is well-known for making robust internal engine components, and these forged pistons for the Honda B18 are a prime example of their work. If you're rebuilding the heart of your B18 engine, whether for street performance or track duty, these pistons are built to handle the demands of a high-performance build. They feature an 82mm bore and a flat-top design with a -2.5cc dish, which is a common configuration for many B18 setups, especially when aiming for a specific compression ratio with the right cylinder head.

Crafted from forged aluminum, these pistons are significantly stronger and more durable than cast pistons. This forged construction means they can withstand higher cylinder pressures and temperatures, making them a solid choice for boosted applications or engines that will be pushed hard. The 82mm size is a popular overbore for the B18, allowing for increased displacement and potential power gains when paired with other performance modifications. It's important to note that this set includes four pistons but does not come with piston rings, so you'll need to source those separately to complete the assembly.

When installing these pistons, remember that proper balancing and clearance are critical for engine longevity. Always refer to the manufacturer's detailed installation instructions and consult with a qualified engine builder to ensure everything is set up correctly for your specific B18 application. These pistons are not CARB approved and cannot be shipped to California.
