Uni Filter UP-4152ST Dual Stage Pod Air Filter 1.5" Inlet Straight

The Uni Filter UP-4152ST is a high-performance dual-stage pod air filter designed for universal applications requiring a 1.5-inch inlet diameter. This straight-design filter measures 1.5" inlet x 3.5" length x 4" outer diameter, making it suitable for carburetors, throttle bodies, and air intake systems on ATVs, UTVs, motorcycles, and other small engines.

Dual-Stage Filtration Technology:

Uni Filter's proprietary dual-stage foam design combines two layers of specially formulated polyurethane foam with different densities. The outer blue foam layer captures larger particles while the inner fine-pore foam traps smaller contaminants, providing superior filtration efficiency compared to paper or single-stage filters. This design ensures maximum airflow while delivering excellent engine protection in dusty conditions.

Key Features:

• Dual-stage foam construction for superior filtration and airflow
• 1.5-inch straight inlet diameter for direct carburetor or throttle body mounting
• Completely washable and reusable—simply clean with Uni Filter cleaner and re-oil
• Universal fitment based on inlet diameter
• Durable polyurethane foam withstands harsh operating conditions
• Sold individually
