Twin Air PowerFlow Kit 4-Stroke Fits Husqvarna KTM FC FE FX SX XC EXC 16-20

If your 4‑stroke could talk, it would beg for the Twin Air PowerFlow Kit — then rip the holeshot just to say thanks. This isn’t some “good enough” filter setup; this is the dirt‑eating, airflow‑boosting upgrade built for serious riders who hate leaving power on the table.

The heart of the kit is a rigid, lightweight billet aluminum cage that replaces your flimsy stock plastic one. Why? Because a perfect, leak‑proof seal means no dirt sneaks past and no horsepower is lost. On top of that, Twin Air adds a backfire‑resistant foam layer inside the filter, giving you extra protection while letting your engine breathe like it’s at sea level all the time.

Whether you’re hammering motos on a Husqvarna FC 450, bombing singletrack on a KTM 350 XC‑F, or lining up for a desert race, this kit keeps airflow maxed and dust out. It’s easy to install, tough as nails, and built to handle whatever abuse you throw at it. More air + less dirt = stronger pulls, sharper throttle, and more fun every ride.
