The new Ness Monster Sucker 90 air cleaner kit features their patented Big Sucker “hidden breather” technology and more filter surface area than any other kit they know of on the market, for maximum performance. Ness hidden breathers are O-ringed at the heads and exit out the mouth of the injector/carb to provide efficient engine breathing, eliminating the need for any external hoses or hardware

The inverted 90° style filter features a built in inverted top to pull in air not only from all sides of the filter but also 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. The filters are re-usable and do not require oil, just rinse and re-use them. Monster Sucker covers are forged from billet aluminum then CNC machined to perfection. Kits are available in the following designs: Standard (without billet cover), Deep Cut, 10-Guage or Beveled styles
Note: 2017-up Touring model applications include a throttle body cover. Forged billet covers can be added at any time to any Ness standard kits that were originally purchased without covers. The Standard kit without cover retails for $249.95-$279.95 and the kits with covers go for $439.95-$479.95.
