Uni Filter Filter Service Kit

Why Proper Filter Servicing Matters for Your Foam Air Filter

Uni Filter has been a pioneer in foam air filtration since the late 1960s, built on a single guiding principle: design an air filter that truly works. Uni Filter chose to use polyurethane foam because of its superior ability to capture particles of dust, dirt, and sand. But even the most capable foam filter is only as good as its maintenance — and that's precisely where the Uni Filter Service Kit comes in.

The Uni Filter Service Kit is the only kit you need when servicing your Uni foam air filters — because without sufficient oil, the air filter will fail to stop harmful dirt particles from entering your engine, resulting in decreased performance and serious engine damage. Regular, proper servicing isn't optional; it's essential to protecting your engine investment.

What's Inside the Uni Filter Service Kit (UFM-400)

The Uni Filter UFM-400 is the brand's signature service kit, bundling everything a rider needs to clean and re-oil a foam filter element in a single convenient package. The service kit contains a 5½ oz Foam Filter Oil aerosol and a Foam Filter Cleaner liquid (14½ oz). These two products are formulated to work in tandem — the cleaner strips away contamination, and the oil restores the filter's dirt-trapping capability.

• Foam Filter Oil: Uni Foam Filter Oil allows maximum airflow while keeping dirt and dust particles out. The air filter foam is wetted with this specially developed oil, which is suspended in the path of dirty air on the strands of the web-like cell structure of the foam.
• Foam Filter Cleaner: Uni Filter Cleaner's powerful agents quickly strip away grease and dirt without damaging air filters — just spray it on, let it soak, and rinse off. It is safe to use on all OEM and performance air filters.

A Reusable System Built for Serious Riders

Uni Filter has been leading the way in powersport air filtration since 1971, producing filters that capture unmatched amounts of dirt, yet can easily be cleaned and used again. The Service Kit is the bridge between rides — it's what allows a Uni foam element to be reused season after season without sacrificing filtration performance.

As the outer foam strands become loaded with dirt particles, the wetted strands downstream start trapping dirt, allowing the entire thickness of the filter to be utilized. This prevents surface loading or air restriction for 80% of the service life of the element — and when it's sufficiently dirty, it can be easily washed, re-oiled, and reused.

Whether you ride motocross, adventure, ATV, or street, pairing your Uni foam filter with the genuine Uni Filter Service Kit ensures you're getting the full performance the filter was engineered to deliver. A Uni air filter truly shows its colors in the dirty, dusty off-roading world — but only when it's properly serviced with the right products.
