A common issue with the stock turbo inlet on Subaru WRXs is that since it is made of plastic, it is prone to cracking. This is especially common as performance increases. With higher temperatures and higher demand, damage to the stock inlet is inevitable. COBB remedies this issue with their performance turbo inlet, which is made of cast aluminum and slightly oversized for smoother operation. The increase in diameter allows the turbo inlet to match the size of the turbo compressor housing. While improvements to airflow are made, COBB also add provisions for the stock or COBB's boost controller and threaded ports for factory-sized PCV and EVAP fittings..

Common Key Features:

• Simple direct fit option made from high-quality cast aluminum.
• Maximizes airflow and port matched to your turbo's compressor inlet.
• Will not crack or fail like your factory turbo inlet.
• Does not require tuning, but still compatible with all COBB OTS maps. A simple upgrade with no-compromise power gains!
• Include mounting provisions for either stock or COBB Electronic Boost Control Solenoids, and threaded ports to accept factory sized PCV and EVAP fittings (included).
• Replaces the brittle factory BPV connection with a more robust reinforced silicone coupler to eliminate a common source of air leaks.
• A captive O-ring is placed on the turbocharger side for a leak-free installation.
• Flats on either side of the inlet allow for the addition of auxiliary pressure sensors, temperature sensors, etc.
• Includes provisions for the stock components to still be used.
