{"type":"firestarter.listing","listing":{"id":"lst_Je5YoKnR","product_name":"APR 2.5 TFSI EVO Turbocharger Inlet System","category":null,"description":"The APR Turbocharger Inlet System outflows the factory components by up to 45%. This is achieved through elimination of the most critical restriction in the entire intake system, the turbocharger inlet pipe. Because of this restriction, no intake airbox / filter design can physically match the gains achieved by upgrading to the APR Turbo Inlet System alone. This is the first step one should take when upgrading their intake system and paves the way for even more gains.\nThe APR Turbocharger Inlet System uses a massive 4” carbon fiber inlet tube that attaches to the factory airbox, or upcoming APR Intake System. Attached to the carbon fiber tube is a massive 4” cast aluminum inlet which is organically shaped to retain the largest possible cross sectional area within the pipe all the way to the inlet of the turbocharger’s compressor cover. Despite the visually odd shape, keeping the cross-sectional area as large as possible is the key to the pipe's performance gains, and greatly outflows smooth looking continuously tapering designs.\nInterlocking adapter rings form a port-matched ideal entrance to the turbocharger, while larger rings (sold separately) provide port-matched support for even larger hybrid turbocharger upgrades. A thick stainless steel heat shield protects the pipe from the hot turbocharger manifold, and an external stainless PCV pipe provides proper PCV placement without impacting the inlet’s design.\n\nThe Restriction\n\n    \n\nThe factory cast inlet pipe is small. It has a maximum internal diameter of 2.8”, at the widest point, and is internally restricted as illustrated in the photos. This pipe is only capable of achieving a maximum of 490 CFM at 28” of H2O when tested alone. Attaching any intake system to this pipe will only result in a lower flow rate, and when using the factory back pipe, airbox, filter and inlet scoop, airflow drops below 430 CFM.\nThe APR Solution\nOur cast inlet pipe is huge and on its own it achieves a staggering 710 CFM with the stock t","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/products/apr25inlet.jpg?v=1551718975","https://cdn.shopify.com/s/files/1/0024/4898/2060/products/CI100038_019.jpg?v=1551718976","https://cdn.shopify.com/s/files/1/0024/4898/2060/products/CI100038_021.jpg?v=1551718978","https://cdn.shopify.com/s/files/1/0024/4898/2060/products/CI100038_022.jpg?v=1551718980","https://cdn.shopify.com/s/files/1/0024/4898/2060/products/CI100038_025.jpg?v=1551718981","https://cdn.shopify.com/s/files/1/0024/4898/2060/products/25tfsi_ea855_evo_inlet_flow.png?v=1551719174"],"price":1126.95,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:21.670Z"},"share_url":"https://firestarter.network/l/lst_Je5YoKnR","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
