Will it fit my 2007 Outback 2.5i?

It is listed for 2005–2009 Legacy and Outback, including 2.5i and 2.5i Limited trims with the EJ25 engine. Check your original alternator's pulley grooves and connector before ordering, since Subaru used more than one setup across trims.

Does it work on the 3.0R six-cylinder?

Yes, the listing covers the 3.0L EZ30 H6 in 3.0R and 3.0R Limited trims. Confirm the pulley and plug on your car match, as the H6 uses its own mounting.

Is 110A enough for extra accessories?

110A is the higher of the factory ratings for these cars and handles normal loads plus modest extras. It is not a high-output alternator for large audio systems or winches.

What comes in the box?

The alternator only. No belt, mounting bolts or instructions are included, so reuse your existing hardware or replace the belt separately if it is worn.

Is it new or remanufactured?

The listing does not state whether the unit is new or remanufactured, and no warranty terms are given. Ask the seller before buying if that matters to you.
