K&N 57-1139 Performance Air Intake System

Part Number:57-1139
K&N FIPK air intakes for select Harley-Davidson Touring motorcycle models increase power by eliminating the restrictive stock OE air cleaner and replacing it with a K&N high-flow air filter and cast aluminum intake tube. These intakes come with an die-cast aluminum throttle-body mounting plate and mounting hardware. K&N high-flow intake systems give your Harley an aggressive appearance while providing a significant increase in airflow resulting in more power.
  • Built-in breathers replace external OE breathers
  • Cast aluminum high-performance intake tube
  • Designed to improve throttle response and engine sound
  • Easy to install, usually in 90 minutes or less
  • Guaranteed to increase horsepower
  • Integrated internal velocity stack
  • Lasts up to 100,000 miles before service is required (depending on driving conditions)
  • Washable and reusable K&N High-Flow cotton air filter that provides outstanding performance and protection
