The UNI NU-4149ST is a high-performance, two-stage foam air filter designed to replace restrictive paper or single-layer filters. It utilizes a dual-layer, open-cell foam construction to maximize airflow while maintaining strict filtration standards. The coarse outer layer captures large debris and heavy dust, while the finer inner layer traps microscopic particles. This design ensures consistent engine protection and performance, even in high-silt or dusty environments. The filter features a heavy-duty sealing surface to prevent air bypass and is fully washable and reusable.
Two-Stage Filtration: Dual-density foam layers provide a two-tier defense against contaminants.
High Airflow: Open-cell foam technology increases air volume to the intake compared to standard filters.
Sealing Base: Thick foam gaskets ensure a secure, airtight seal against the airbox.
Serviceable: Designed for repeated cleaning and re-oiling with standard foam filter maintenance products.
Durability: High-quality adhesive construction resists breakdown from fuels and cleaning solvents.
Made in the USA: Manufactured to high-tolerance specifications for consistent fit and finish.
Part Number: NU-4149ST
