UNI Filter Multi-Stage Competition Air Filters

5.0 out of 5 stars 12 Customer Reviews

Leave it to UNI Filter multi-stage competition air filters to launch the performance air filter into the next century. The lifeblood of your air intake system is the air filter, and a high-quality filter is guaranteed to breathe new life into your system. The unique two-stage design of these air filters leaves the outer layer dry for longer periods of power-producing airflow--or oil them for those times when the conditions are soggy. UNI Filter multi-stage competition air filters trap more dirt, have a snug fit, and afford longer rides with more power.
