The Cast Piston 94.0mm Bore Toyota 4.6L V8 06-22 from SEALED POWER is a direct-fit replacement component engineered for high-performance Toyota V8 applications spanning model years 2006 through 2022. As a mechanic and automotive enthusiast, you know that factory pistons endure extreme thermal and mechanical stress during both street driving and modified engine builds. This cast piston delivers the durability and precision clearances required for reliable power delivery, whether you're restoring an original engine or building a custom stroker platform.

SEALED POWER's cast construction provides excellent strength-to-weight characteristics and superior heat dissipation compared to lower-grade alternatives, critical for sustained boost applications or extended high-RPM operation. The 94.0mm bore diameter is precisely machined to OEM specifications, ensuring correct piston-to-wall clearance and ring groove geometry that maintain compression integrity and minimize blow-by. Cast pistons are engineered to handle the shock loads common in turbocharged or nitrous-assisted engines while maintaining dimensional stability across repeated thermal cycling, making them the preferred choice for both daily drivers and weekend track machines.

This piston is ideal for Toyota 4.6L V8 engine builders and technicians performing top-end rebuilds, complete short-block assembly, or performance upgrades on 1UZ-FE and 2UZ-FE platforms. Installation requires proper honing to achieve correct bore finish and precise piston pin fitment; verify all specifications with your engine's factory documentation or performance build sheet before assembly. Whether you're replacing worn factory pistons or upgrading a high-mileage engine, SEALED POWER's proven track record in OEM and aftermarket applications ensures reliable performance and long-term durability.
