The APR Carbon Fiber Intake System (CI100043) is a comprehensive performance upgrade designed to replace the entire restrictive factory intake tract from the front inlet scoop to the turbocharger inlet. By utilizing carbon fiber construction, APR achieves thinner wall thicknesses to maximize internal diameter and creates organic shapes that fit the tight B9 engine bay, resulting in a system that flows 31% better than stock.

  • Complete system includes carbon fiber airbox, high-flow filter, carbon inlet piping, and billet turbo adapter
  • Large 7-inch x 7-inch washable pleated cotton gauze filter with 4-inch outlet and 5.5-inch frontal inlet
  • Maximized inlet piping diameter reduces pressure drop for improved turbocharger efficiency and faster spooling
  • Billet turbo adapter ring ensures a secure fit to the factory turbocharger
  • Verified gains of up to +19 AWHP and +20 AWFT-LBS of torque over stock when paired with APR Stage 1 (93) tuning
  • Airbox design includes additional flow paths oriented away from engine heat
  • Includes new OEM gaskets and all required installation hardware

This system delivers a significant increase in airflow and a more aggressive engine note while adding a premium carbon fiber aesthetic to the engine bay.
