Wiseco Hyundai 4B11 (K651M86 w/ 86mm Bore 10.5:1 CR) Custom Piston - Single

Wiseco is well-known for making strong internal engine components, and this custom piston for the Hyundai 4B11 engine is no exception. If you're rebuilding your engine or looking to upgrade its performance, this single piston is built to handle the demands of a performance build. It features an 86mm bore and a 10.5:1 compression ratio, which is a common target for builds aiming for a noticeable bump in power and responsiveness.

This piston is constructed from forged aluminum, a material chosen for its strength-to-weight ratio, which is crucial for high-performance engine internals. The forged process creates a denser, more durable piston than cast alternatives, helping it withstand higher cylinder pressures and temperatures. This specific piston is designed as a single unit, allowing for custom configurations or replacement of individual damaged pistons in your 4B11 engine.

Keep in mind that this piston is not CARB approved and cannot be shipped to California. For optimal results and longevity, ensure you consult with a professional engine builder or refer to Wiseco's technical documentation for proper installation and compatibility with other engine components.
