Ness Inverted Air Cleaners

invertedac1invertedac2invertedac3About 10 years ago Ness introduced the patented Big Sucker™ air cleaner. This new series of air cleaners is using the same technology, but improves it thanks to an inverted filter.

This technique maximizes air flow by pulling more air from the face instead of the sides, the traditional way most of today’s air cleaners still work. Made from forged billet aluminum and available in 3 different styles Beveled (top left), Deep Cut (top right) and Slot Track (bottom left)

Filter is USA made, pre-oiled, with inverted pleated on top and pleated on sides. Forged billet aluminum backing plate features with proven radius air inlet and hidden breather hardware. All mounting hardware, gaskets, and necessary components are included. For 1988-up Sportsters, 2008-up FLT’s Big Twin (except Fly-By-Wire) MSRP $399.95.  .

    I’ll pass.

    P.S. Don’t forget to save your stock air cleaner. If you reinstall the stock unit before before you sell your bike, it’ll be one of a kind and you’ll get more money for your bike.

    As always, thank you for the support!

    Just to add a few things about the Inverted Series Air Cleaners:

    -These kits pull air from the sides and from the top of the filter, the top utilizes the machined velocity stacks integrated into the forged filter cover

    -These kits utilize our Big Sucker hidden breather technology where each hidden breather is o-ringed at the heads and exits at the mouth of the injector/carb to provide efficient engine breathing and a virtually closed loop system. This eliminates the need for any external hoses or hardware, and oil leeks associated with hoses/hose clamps

    -In addition to our hidden breather technology the forged aluminum backing plate has a radius air inlet for unobstructed airflow and we even machined the back of the plate to reduce as much weight as possible

    – Our filters are hand poured in the USA. We are now using a black synthetic material wrapped in a stainless steel jacket that does not require oil and is water resistant. This provides more filtration, protection from road debris, and eliminates the need for a rain sock

    -All filter housings/covers are made from forged billet aluminum and is now available in 4 styles. Slot Track, Deep Cut, Bevelled, and 10-Gauge

    Thank you & Happy New Year,
