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, foolproof fit.
Twin Air's PowerFlow kit comes with a rigid, lightweight, billet aluminium cage that provides a tight seal to the airbox and replaces your flimsy plastic stock cage.
A TwinAir Powerflow Kit includes a pre-oiled Twin Air filter, a special aluminium 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 aluminium cage with a special backfire-resistant layer of foam laminated to the inside of the filter.
PowerFlow kits are available for many models, and we're constantly adding new ones to fix issues with OEM airboxes.
