K&N Universal High-Flow Air Filter – 5" Flange x 8-1/2" Base x 5" Height
The K&N Universal High-Flow Air Filter is a versatile performance air filter designed for a wide range of applications, including racing vehicles, generators, snowmobiles, tractors, and custom intake systems. With a 5" flange diameter, 8-1/2" base diameter, and 5" height, it offers excellent airflow while providing effective filtration.
The ultra-strong molded pliable rubber flange absorbs vibration and allows for secure attachment, and it can be stretched up to 1/16" (1.5mm) to fit in-between sizes. Constructed with K&N’s signature layered, oiled cotton media, this washable and reusable filter delivers superior airflow compared to stock paper filters, supporting increased horsepower and improved engine efficiency. Ideal for custom builds or equipment where a standard filter won’t fit.
