The APR CI100038 Turbocharger Inlet System outflows the OEM components by up to 45% through eliminating the critical restriction in the OEM turbocharger inlet pipe. This is the first step one should take when upgrading their intake system and paves the way for even more gains. The APR Turbo Inlet System uses a massive 4 inch carbon fiber inlet tube attached to a massive 4 inch cast aluminum inlet which is organically shaped to retain the largest possible cross sectional area throughout the inlet all the way to the turbo intake.

The optional CI100038A Filter brings the airflow improvement up even further from a 45% gain to a 60% gain for even more performance!

Benefits of the APR CI100038 Turbo Inlet System:

  • Increases flow from 490 CFM to 710CFM
    A 45% improvement over the OEM inlet.
  • Cast aluminum elbow with 4 inch inlet
    Organically shaped for maximum airflow.
  • Full 4 inch carbon fiber inlet pipe
    Featuring smooth transitions and minimal bends.
  • CNC machined inlet adapter
    Compatible with the OEM turbo, or optionally, the TTE625, TTE700, or GTX3582 turbos.
  • Compatible with OEM or aftermarket intakes
    Attaches to the OEM airbox or any airbox designed to mate with the OEM inlet pipe.

APR CI100038 Inlet Design:

APR’s engineers tested a multitude of designs and quickly determined the elbow could not act as an upgrade on its own because of the significant increase in diameter required. The rear inlet pipe also had to be upgraded to utilize this larger diameter. Other designs which offer a continuously reducing taper and may look smoother, are in fact extremely limited. At 3.5”, 550 CFM is achievable, enlarging the tapered design to 4” only results in a paltry 10 CFM gain. In contrast, the organically shaped APR inlet system achieves an astounding 710 CFM under the same test.

APR CI100038 Turbocharger Inlet Vehicle Fitment:
