Cobb 15-21 Subaru WRX / 14-18 Forester XT Cast Turbo Inlet

The Cobb Cast Turbo Inlet replaces the restrictive factory plastic inlet on 2015-2021 Subaru WRX and 2014-2018 Forester XT models. This direct bolt-on upgrade features a larger internal diameter and smoother flow path to increase turbo efficiency. Drivers experience faster spool times, sharper throttle response, and higher boost potential across the RPM range.

Key Features

  • Cast Aluminum Construction: High-strength aluminum casting withstands high boost pressures and heat for long-term durability under demanding conditions.
  • Larger Inlet Diameter: 2.75-inch ID (vs. stock 2.25-inch) reduces restrictions and turbulence for improved airflow volume and velocity into the turbo compressor.
  • Smooth Internal Geometry: Precision-machined surfaces eliminate flow disruptions found in OEM plastic designs, enhancing compressor efficiency and reducing lag.
  • Secure O-Ring Seal: Large silicone O-ring provides airtight connection to the turbo inlet elbow, preventing boost leaks common in stock units.
  • Black Powdercoat Finish: Corrosion-resistant coating protects against engine bay elements while maintaining a clean underhood appearance.

Product Notes

  • Direct replacement for OEM part no cutting or modifications required.
  • Pair with Cobb SF Intake for full intake tract optimization.

Installation Notes

  • Professional installation recommended.
  • Remove stock intercooler inlet pipe and turbo inlet elbow torque inlet flange bolts to 7 ft-lbs.
  • Compatible with stock turbo hardware and aftermarket cold air intakes using stock-style couplers.
