Large Three Layer Performance Air Filter: Momentum’s unique filter-to-housing interface was built to feature the largest air filter possible. This 6 IN tall 360-degree radial flow air filter features a 4-1/2″ flange and our oil-free Pro DRY S media with three layers of synthetic media for maximum convenience. Its progressive layering provides great filtration efficiency and dust holding capacity, while not requiring the use of oils. This media is best suited for street use. Its inverted top makes for more filter surface area, resulting in longer service intervals._x000d_Unique One-Piece Housing: The sealed heat-resistant housing, constructed of XPLE (cross-linked polyethylene) polymer, features our patent-pending filter-to-housing interface and a clear sight window that allows for hassle-free filter inspection. An aluminum heat shield panel on the side of the housing deflects hot air emitted from the turbocharger, ensuring the system’s two air inlets bring in the coolest air possible. In addition to the massive auxiliary air inlet, this intake utilizes the vehicle’s OE air inlet with no additional hardware._x000d_Reinforced Silicone Intake Tube: This intake system utilizes a flexible silicone intake tube that is reinforced with four layers of nylon material, making it virtually resistant to wear and deterioration. It includes a vacuum hose fitting, along with an aluminum insert that easily mates the intake tube to the air filter._x000d_Hassle-Free Installation: Stainless-steel clamps and a silicone inlet trim are included for strength and durability. Momentum GT’s innovative filter-to-housing design minimizes the total number of parts, making for a fast and easy installation._x000d_Fitment Note: This item will only fit models equipped with 45TFSI engine.

K&N 57i Series induction kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. The extra surface area of these open-air air filters provide even more airflow at lower restriction than a K&N O/E replacement filter which is limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adapters are made from high quality materials such as steel, aluminum, silicon or reinforced nylon to ensure long life. 57i Intakes are not legal for use in California and other US States adopting California emission standards.
