Show original supplier description
The Tomei TB401B-FIT29 is a genuine Tomei repair part designed as a turbocharger fitting with an M10 4AN connection and a 51mm height. This component is intended for use with specific Tomei turbocharger kits and ensures proper fluid or oil flow within the system. This fitting is specifically engineered for a precise fit on the 2020, 2021, and 2022 Subaru WRX models. However, some users have reported that one side may not fit due to the TGV sensor, and it can be a tight fit regardless. Installation may require maneuvering around or modifying the TGV sensor to allow the inlet to clear.
