In cooperation with the Kawasaki Racing Team we completed the development of the new air filter products for the KXF450 2016.

Besides the original replacement filter we also developed a special aluminum cage (PowerFlow Kit) for more airflow. The new system is easy to install and provides the best performance and protection for the engine. We also have the following products available for extra protection during extreme weather conditions: Dust Covers, Rain Covers and GP covers.


Nineteen-year-old Tim Gajser took an historic MX2 World Championship title today for the Honda Gariboldi Racing Team.

It’s been a triumphant and meteoric year for Gajser and Honda Gariboldi Racing. In Arco di Trento in April he scored his career first MX2 Grand Prix victory on the CRF250RW. Since, four more victories have followed, including a further three trips to the podium.


Twin Air released two instruction videos: one video Oiling your foam air filter and the second one Cleaning your foam air filter. the air filter. In these videos our customers will be informed ‘how to’ maintain your foam air filter. The videos are made in close cooperation with Factory Kawasaki Racing Team.

Twin Air Tech Tip: KTM Powerflow Kit 2- and 4-stroke
Sunday, 26 February 2012 00:01
Twin-Air-154215CNAfter a succesfull season and a lot of testing Twin Air developed, in cooperation with KTM Racing, a new Powerflow Kit for the 2 and 4-stroke engines.

The new aluminum filter cage is completely redesigned to increase airflow and performance. The higher support arms on the filter cage makes sure that the foam is not vibrating as the intake is closely positioned to the foam material. Also, the support arms are now shaped to increase airflow.

The new air filter (154215FRN) has a new shape to improve fitment, increase surface area and less glue seems.
Twin-Air-KTM-Old-NewThis means more air and better protection for the engine.

To gain extra air flow, Twin Air developed a supercross (154215SCN) and supermoto (154215SMN) type air filter. The Supermoto Air Filter has larger pores and will provide more air, which results in more power. In extreme riding conditions, we advice to use the Grand Prix Covers for extra protection (160000GPBK).

KTM-Factory-RacingAs a result of the intensive cooperation with KTM Racing, we developed the optimal solution for the airbox.

Currently Ryan Dungey, Marvin Musquin, Ken Roczen, Jeffrey Herlings, Jeremy van Horebeek and Jordy Tixier are riding with these new Powerflow Kits.

To order these new parts, you simply add an N behind the part number. Both former and new filter model fits both old and new aluminum cage. For a full applicationlist see below.
