K&N 57-1133 Performance Air Intake System

The K&N 57-1133 Cold Air Intake System is engineered to replace the factory air filter and intake housing in a range of Polaris Ranger RZR models, delivering a guaranteed boost in both horsepower and torque. It features a free-flowing aluminum intake tube that enhances airflow to the engine for improved performance. The system includes a washable and reusable High-Flow Air Filter™ made with oiled cotton media, safeguarded by a protective foam wrap and enclosed housing to shield against heat and harsh conditions. Its oversized conical design supports extended use—up to 100,000 miles between cleanings under normal highway conditions. Designed for convenience, the system can be installed in 90 minutes or less with common hand tools.
