Uni Multi-Stage Competition Air Filters are unsurpassed in airflow, dirt stopping and overall performance. And they produce more horsepower and more torque than any other air filter. Uni's revolutionary two stage air filter is the only filter that comes apart for maximum airflow and ultimate cleaning.

• The large pore, pre-filter captures the bigger particles.
