Volant 09-13 Audi A4 2.0T / 11-13 A5 2.0T Powercore Closed Box Air Intake System

Volant Air Filter Box: Our Cross-Link polyethylene box is engineered to each specific application for low restriction and an increase in air volume. It insulates and protects the filter from engine heat, moisture, dust and debris to provide colder air to the engine for an increase in horsepower. Volant Air Duct: Factory air inlet ducts use sound baffles and awkward bends which restrict flow. Our Cross-Link polyethylene air ducts are sculptured to give the engine less restrictive breathing. Incorporating larger diameters and unique bends, that can't be duplicated with metal ducts, allow for maximum airflow velocity and throttle response. NEW Volant Filters with PowerCore Filtration Technology: This air filter is the most revolutionary on the market. Manufactured by Donaldson to Volant's applications, this filter uses advanced technology for improved efficiency. This material is a high-quality synthetic, that won't deteriorate as easily as traditional paper element and cotton/gauze filter media, while also providing vastly improved filtration up to 99.97%. In addition, it's water resistant and never needs oiling. PowerCore Filtration Technology works by directing air into the front of the filter, where it is channeled into its fluted design. The channels are alternately sealed, allowing air to enter through an open flute and forcing it to exit out an adjacent flute. This allows the air to be filtered in one pass through the filter media with less restriction, allowing clean air to enter your engine for increased airflow and higher filtration efficiency. This technology allows the filter to include a 4 year or 100,000 miles warranty when used in urban conditions. High Performance Silicon Connectors: Our silicone hose connectors provide flexibility while maintaining strength and thermal stability. They won't crack or deform over time like rubber connectors. Stainless Steel Clamps: We only use marine-grade, stainless steel clamps that provide optimal performance to provide a solid seal that won't loosen or deteriorate.
