To give you the correct torque figure, please tell me:
* Which engine is in your 2006 Subaru Legacy? You can find this information on your vehicle's registration documents, owner's manual, or by looking at the engine itself (usually a sticker on the engine block).
* The displacement of the engine. (e.g., 2.5L, 3.0L)
Once I know the engine, I can tell you the torque output.
