Overview 

The UEM Piston 1FZ 103/STD Stroke Flat is a high-performance forged piston designed for Toyota 1FZ-FE engines with a standard stroke configuration. Featuring a 103mm bore and a flat-top crown, this piston is ideal for naturally aspirated or mildly boosted applications where maintaining a higher compression ratio is beneficial. The flat-top design enhances combustion efficiency and power output, making it suitable for performance builds that do not rely on extreme forced induction. Constructed from high-strength forged materials, this piston ensures exceptional durability, capable of withstanding the high pressures and temperatures common in motorsport, off-road, and high-performance street builds.
