APR Turbocharger Inlet System For 8V/8S Audi TTRS/RS3 2.5TFSI - Cast Inlet Kit Only

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.

The APR Turbocharger Inlet System uses a massive 4” carbon fiber inlet tube (sold separately) 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.
