Polini Dual-Layer Air Filter: Vespa GTS

Performance Breathability: Polini Dual-Layer Air Filter

Give your engine the protection and airflow it deserves with the Polini Blue Air Filter. Designed specifically for the Vespa GTS and GTV series, this high-performance sponge features a sophisticated two-stage filtration system. Unlike standard single-layer filters, Polini’s dual-density foam captures both large debris and microscopic dust, ensuring your intake remains clean while maximizing oxygen flow for better combustion.

Technical Performance Features

• Dual-Stage Filtration: Features a 30 PPI (pores per inch) black outer layer to trap coarse dirt and a 60 PPI blue inner layer to stop fine particulates from entering the cylinder.
• Self-Extinguishing Foam: Manufactured from specialized polyurethane foam that is designed to be flame-retardant for added safety within the airbox.
• Thermal Bonded Construction: The two layers are joined via a special hot-forming process that ensures they never delaminate, maintaining consistent airflow across the entire surface.
• High-Flow Efficiency: Engineered to provide less resistance than the stock filter, aiding in crisper throttle response and improved engine cooling.
