The Monster Sucker Air Cleaner uses hidden breather technology to provide a reliable intake that enhances engine performance.
Hidden breathers are O-ringed at the heads and exit out the mouth of the throttle body to provide efficient engine breathing without external hoses or hardware.
The synthetic filter media is water-resistant, often eliminating the need for a rain sock, and is reusable — no oil required; simply rinse and reuse.
The filter has a built-in inverted top to draw air from all sides for increased performance-gaining airflow.
Will not fit models with fairing lowers. Fits '01-'17 Twin Cam Delphi EFI and '99-'06 Twin Cam CV carb models.
