Twin Air PowerFlow Air Filter Kit

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.

A Twin Air Powerflow Kit includes a pre-oiled Twin Air filter, a special aluminum cage and all necessary mounting hardware.

Twin Air PowerFlow Kit for 4-Stroke models:
Replace your air-restricting stock backfire screen with our New PowerFlow kit. The kit includes a rigid, lightweight, billet aluminum cage with a special backfire-resistant layer of foam laminated to the inside of the filter.

Twin Air PowerFlow Kits for ATV's:
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 to fix issues with OEM airboxes.
