Motorcycle 2 Stroke Power Flow Kits

The best filter in the world can't do its job if there are leaks in the seal of the airbox. That's why Twin Air provides a complete line of products to ensure a leak-proof, fool proof fit. Twin Air's PowerFlow kit comes with a rigid, lightweight, billet aluminum cage that provides a tight seal to the airbox and replaces your flimsy plastic stock cage.

Don’t let your stock set-up rob you of power and engine reliability. These kits eliminate leaks and provide more air for power, but the filter can still be removed in a snap for cleaning. The new generation PowerFlow kit converts the filter mounting system from a clamp on filter to a filter cage and wing bolt mounting system. This new flange system allows for the use of a Twin Air Air Box Cover for washing the air box.

PowerFlow kits are available for many models, and we're constantly adding new ones. Please call or email for a complete listing.
