Overview 

The UEM TB48/1FZ-FE 103mm Skinny Flat piston is built for high-performance engine applications that demand increased displacement and efficient combustion. With a 103mm bore, it's ideal for overbored versions of the Nissan TB48 and Toyota 1FZ-FE engines. Its flat-top crown and slim profile are engineered to enhance combustion efficiency and support higher compression ratios, making it suitable for both naturally aspirated and turbocharged setups. Crafted from high-strength forged aluminum alloy, this piston provides excellent durability and reliability under extreme thermal and mechanical stress, making it a strong choice for performance and motorsport builds.
