Product Description

The TS-SU-881-3 HD Cast Aluminium 3" Hard Turbo Inlet from Torque Solution is engineered for performance Subaru EJ-series turbocharged platforms, specifically the WRX (2002-07) and WRX STI (2004-21). The OEM corrugated rubber turbo inlet hose is often restrictive and prone to failure under boost. This hard pipe upgrade replaces that with a rigid cast aluminium unit and 3" silicone coupler, improving airflow into the turbo and supporting higher boost levels with less lag.

Installation is straightforward: the kit is direct-fit for the specified vehicles, includes all necessary hose clamps, couplers, and fittings, and works with both recirculated and speed-density intake configurations. While it doesn't directly increase boost, the smoother airflow path and robust construction make it an ideal upgrade for tuned or track-oriented builds.

Important fitment note: This part covers Subaru WRX models from 2002-07 and WRX STI models from 2004-21 inclusive. Verify that your vehicle uses the EJ20 or EJ25 turbo engine and that the turbo inlet size is compatible with the 3" (76 mm) hose. Fitment for non-EJ engines (e.g., FA/FB/FA24) or other model years is unconfirmed at time of listing.
