Pro Design Pro Flow Air Filters: Purpose-Built for Powersports Performance

When stock airbox restrictions hold back your ATV or powersports machine, Pro Design offers a direct answer in the form of their signature Pro Flow air filter systems. Rather than simply swapping one filter for another, Pro Design's approach rethinks the entire intake path — and the results speak for themselves on the trail, track, and dunes. Browse the full selection of air filters to find the right fit for your machine.

The Pro Flow System: More Than Just a Filter

The centerpiece of Pro Design's air filter lineup is the Pro Flow Kit, a complete intake upgrade designed to replace the factory setup from the ground up. The Pro Flow kit includes a billet base plate which dramatically improves performance by directing and channeling airflow at a much higher volume for superior power gains. This isn't a generic bolt-on — the adapter is precision CNC-machined from billet and features an O-ring seal for easy and reliable installation.

One of the most practical advantages of the Pro Flow design is its flexibility in the field. In dry riding conditions, with the Pro Flow Kits, you can completely remove the air box lid and maximize your air intake, while the filter remains in place without the restriction inherent with the stock mounting lid. That means more breathing room for the engine exactly when you need it most.

Multi-Stage Filtration for Real-World Protection

Airflow gains are only half the equation — keeping dirt and debris out of your engine is equally critical. Pro Design addresses this with a layered filtration approach. Each kit includes a positive O-ring seal, a 2-stage high volume foam air filter with a 3rd stage filter wrap, and all mounting hardware. The positive O-ring seal provides an absolute barrier against sand and debris, which is especially important for riders who push their machines through dusty or sandy terrain.

For riders who already own a Pro Flow intake system, Pro Design's replacement Uni Filters are designed to replace the stock restrictive air filter and adapter, while forming a perfect seal at the front of the filter for a dramatic improvement over stock by preventing dirt and debris from getting into your intake.

Broad Vehicle Coverage

Pro Design's air filter solutions are engineered for a wide range of popular ATV and powersports platforms, including models from Yamaha, Kawasaki, and more. Pro Design Airbox Filter Kits replace the faulty stock and restrictive air filter and adaptor to give you the performance you want. Whether you ride a sport quad, a utility ATV, or a dedicated race machine, Pro Design offers fitment-specific kits so every component seals and performs as intended — no modifications required.
