Title: Monster Sucker Air Cleaner Kits
Option: Deep Cut
Color: Black

  • Monster Sucker kit features our patented Big Sucker "hidden breather" technology and more filter surface area for maximum performance
  • Hidden breathers are O-ringed at the heads and exit out the mouth of the throttle body to provide efficient engine breathing, eliminating the need for any external hoses or hardware
  • Filter features a built-in inverted top to pull in air not only from all sides of the filter but also from the front, which results in more performance-gaining airflow
  • Each filter is constructed from synthetic material that is water-resistant, which in most cases eliminates the need for a rain sock
  • Filters are re-usable and do not require oil, just rinse and re-use
  • Kits include Arlen Ness forged billet covers
  • Replacement air filter fits all Monster Sucker air cleaners; sold separately
  • Fit with fairing lowers

Important Notes

NOTESWill not fit models with fairing lowers.
