4into1 Uni Filter UP-107 1" Clamp-On Breather — Washable Urethane Foam, Oil-Treated 1" Fit

The 4into1 Uni Filter UP-107 1" Clamp-On Breather is a washable, oil-treated urethane foam breather that prevents dirt and debris from entering your ATV engine while fitting easily to a 1" clamp-on port.

Designed for off-road and utility vehicles, the Uni Filter UP-107 uses open-cell polyurethane foam combined with a specially formulated filter oil to trap dust, mud, and contaminants before they reach engine internals. Its washable construction and durable urethane material make it a practical, long-lasting replacement or upgrade for machines that need reliable airflow filtration in harsh conditions.

How does the Uni Filter UP-107 keep dirt and dust out of my engine?

The filter combines porous foam with tacky filter oil: particles become captured in the open-cell structure and adhere to the oil rather than passing through to the intake. This dual-action approach balances high airflow with strong contaminant retention for improved engine protection.

• Open-cell urethane foam captures particulates while maintaining airflow
• Specially developed filter oil increases particle adhesion
• Washable design lets you remove trapped debris and re-oil the element
• Clamp-on 1" fit provides a secure, simple installation

What maintenance does this washable foam breather require?

Maintenance involves cleaning the foam, drying it thoroughly, and reapplying filter oil to restore its sticky capture properties. Regular service intervals depend on use—inspect after heavy, dusty rides and clean when visibly contaminated or airflow feels restricted.

• Remove and rinse the foam in warm water with mild detergent
• Allow the foam to dry completely before re-oiling
• Use a quality foam filter oil and apply evenly to saturation
• Reinstall using the 1" clamp for a snug fit

Will the Uni Filter UP-107 fit my ATV or side-by-side?

The UP-107 is made as a clamp-on 1" breather; confirm that your machine accepts a 1" clamp-on vent or breather port. It commonly adapts to many aftermarket and OEM breather openings, but measure your specific connection before purchase to ensure compatibility.

• Designed for 1" clamp-on breather ports and vent tubes
• Flexible foam allows minor size variation and secure sealing
• Works well as a replacement for worn or clogged breathers
• Check dimensions and clamp type on your vehicle before ordering

What are the construction and material benefits of this model?

The UP-107 uses a new washable urethane material engineered for durability and consistent pore structure. That construction offers resilient filtration performance, easy cleaning, and longer service life compared with cheaper disposable alternatives.

• New UNI washable urethane material resists tearing and collapse
• Uniform open-cell structure for predictable airflow and capture
• Washable and reusable to reduce replacement frequency and cost
• Low-profile clamp-on design simplifies installation and removal

Who is this for: The 4into1 Uni Filter UP-107 is aimed at riders and mechanics who need a simple, durable breather solution for ATVs, UTVs, dirt bikes, or other small engines that use a 1" clamp-on vent. It's particularly useful for off-road enthusiasts who encounter dusty or muddy conditions and prefer a washable, serviceable filter over disposable elements.
