4into1 Uni Filter UP-107 1" Clamp-On Breather for ATV/Off-Road — Washable Foam, 1" Fit

The 4into1 Uni Filter UP-107 1" Clamp-On Breather is a washable, clamp-on foam breather designed to keep dirt, dust and mud out of your ATV or off-road engine while allowing reliable airflow.

Built around proven open-cell polyurethane foam and formulated filter oil, the Uni Filter UP-107 offers a compact clamp-on breather solution for riders who need dependable contamination control without bulky housings. Its washable urethane material and simple 1" clamp-on design make it easy to install, maintain and reuse season after season. This product is targeted at recreational and utility riders who want better engine protection from airborne debris while maintaining consistent intake flow.

How does the UP-107 clamp-on breather protect my ATV engine?

The UP-107 uses open-cell urethane foam combined with tacky filter oil to trap dust and grit before they reach sensitive engine parts. Dirt particles stick to the oiled foam while clean air passes through, reducing wear and extending component life when properly serviced.

• Open-cell polyurethane foam captures a wide range of particle sizes.
• Filter oil increases particle adhesion to the foam matrix.
• Clamp-on fit seals to standard 1" breather nipples for direct protection.

What makes this Uni Filter different from disposable paper breathers?

Unlike single-use paper elements, the UP-107 is made from washable urethane that you can clean, re-oil, and reinstall. That reduces waste and long-term replacement cost while preserving filtration performance when maintained correctly.

• Washable and reusable foam construction for multiple service cycles.
• Durable urethane resists degradation from oil and environmental exposure.
• Compact clamp-on design avoids modification to existing housings.

How do I install and maintain the 1" clamp-on breather?

Installation is straightforward: slide the UP-107 over a 1" breather nipple and secure the clamp. For maintenance, remove the element, wash out contaminants with a mild cleaner, let it dry, reapply filter oil evenly, and clamp back into position.

• Slide onto a standard 1" breather nipple and tighten the clamp until snug.
• Clean with a non-caustic detergent, rinse, and allow to air dry fully.
• Apply a thin, even layer of appropriate foam filter oil before reuse.

Will this breather affect airflow or performance?

The UP-107 is engineered to balance airflow and filtration for typical ATV and off-road applications. Properly oiled and installed, it provides effective contamination control with minimal restriction under normal operating conditions.

• Designed for everyday off-road use where breathers need both flow and filtration.
• Thin, open-cell foam supports steady airflow while capturing debris.
• Recommended for intake breather or crankcase vent applications matching the 1" size.

Who is this for: The 4into1 Uni Filter UP-107 1" Clamp-On Breather is ideal for ATV, UTV and small off-road vehicle owners who need a compact, reusable breather solution. It suits riders and mechanics who value easy servicing, lower long-term costs, and improved engine protection in dusty or muddy environments. If you have a standard 1" breather nipple and want a reliable, washable foam element to reduce airborne contamination, the UP-107 is a practical, straightforward choice.
