aFe Momentum GT Cold Air Intake with Pro 5R Filter for Audi A4 (B9) 2017-2025 2.0L 45 TFSI, Part 50-70032R

Large Five Layer Performance Air Filter: Momentum's innovative 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 pre-oiled Pro 5R media with five layers of progressively finer cotton gauze media for maximum performance. It provides your engine with the largest amount of high-flowing air and delivers the highest power gains in most cases. This media is perfect for street and/or track use. Its inverted top makes for more filter surface area, resulting in longer service intervals. Unique One-Piece Housing: The sealed heat-resistant housing, constructed of XLPE (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. 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. 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. Fitment Note: This item will only fit models equipped with 45TFSI engine. Momentum GT Cold Air Intake System w/ Pro 5R Filter Audi A4 (B9) 17-25 L4-2.0L (t) 45TFSI

Brief Description: The aFe Momentum GT Cold Air Intake System with Pro 5R Filter is designed for Audi A4 (B9) models equipped with the 2.0L 45 TFSI engine. Part 50-70032R combines a high-flow, five-layer oiled cotton gauze filter with a sealed intake housing to deliver cooler, denser air to the engine. The system is engineered for improved airflow, strong performance, and a clean installation using the vehicle’s original air inlet.

Performance Benefits: The large 360-degree radial-flow filter and inverted top maximize usable filter surface area, helping support longer service intervals and consistent airflow for street or track use. Testing shows the intake flows 305 CFM at 7 inches of water and outflows the factory intake by 11%, with gains of up to 6 horsepower and 7 lb.-ft. of torque. A heat-blocking aluminum panel and dual air inlets help reduce exposure to hot turbocharger air.

Construction and Installation: The one-piece XLPE polymer housing features a clear sight window for quick filter inspection and a patent-pending filter-to-housing interface that minimizes hardware and simplifies installation. The reinforced silicone intake tube uses four layers of nylon reinforcement for durability and includes a vacuum hose fitting and aluminum filter adapter. Stainless-steel clamps and a silicone inlet trim are included. This application fits select 2017-2025 Audi A4 models equipped with the 45 TFSI engine; verify vehicle configuration before ordering.
