The TFI Racing Airbox Inline Polished Alloy is a practical solution for builders looking to create a custom cold air intake setup with a clean, high quality finish. Designed with a 4 inch 102mm inlet and outlet, it suits a wide range of performance intake applications where smooth airflow and a secure inline fit are important. The polished alloy construction adds durability while delivering an attractive appearance that complements custom engine bay builds.

With a cylindrical body measuring 10.1 inch 257mm in total length and an outside diameter of 5 inch 127mm, this airbox is compact enough for tight installations while still providing the volume needed for efficient airflow management. It is designed to help feed the engine cooler outside air, supporting improved performance potential by reducing the intake of warm under bonnet air. This makes it a useful upgrade for street, touring, and custom performance vehicles.

The included air filter adds convenience and helps make this a versatile intake component for fabrication projects. Whether you are replacing a restrictive factory intake or building a custom setup from scratch, the inline design makes routing simple and adaptable. The polished alloy finish also gives the system a professional look that suits both functional and show focused builds.
