If you're rebuilding the engine in your Honda with a K20A or K20A2 engine, a set of high-performance pistons like these from CP Pistons can make a big difference. These are designed to handle increased stress and heat, making them a solid choice for builds that aim for more power or need to replace worn-out stock components. This specific piston has a bore of 86.5mm and is sized at +0.5mm, meaning it's intended for an engine block that has been bored out to match this dimension for a precise fit.

CP Pistons are well-known in the performance engine world for their robust construction. This piston features an 11.5:1 compression ratio, which is a notable increase over stock, helping to generate more power from your fuel. They are forged, a process that creates a very strong and durable piston capable of withstanding the higher cylinder pressures found in modified engines. This strength is crucial for reliability when you're pushing your K-series engine harder.

Remember that this is a single piston. You'll need to order the correct quantity to match your engine's cylinder count, and ensure your engine block has been machined to the 86.5mm bore size. It's also important to note that these pistons are not CARB approved and cannot be shipped to California.
