TWIN AIR POWERFLOW KIT KTM 4 STROKE (2007-2011)

The best filter in the world can’t do its job if there are leaks in the seal of the airbox. Twin Air’s PowerFlow Kits ensure a leak-proof, fool-proof fit with a rigid, lightweight aluminum cage that replaces your flimsy, plastic stock cage and, when needed, a billet-aluminum flange that bolts tight to your airbox.

PowerFlow Kits are custom-designed to each unique application for superior airflow, improved sealing surface, removal of the restrictive backfire screen, and ease of service.

All Kits include a BIO Factory Pre-Oiled Air Filter. Replacements are available separately.
