Our take on the 11024-270XP High Output Alternator for Subaru Outback, Legacy, Impreza

A 270-amp high-output alternator built to bolt directly to the OEM mounts on Subaru Outback, Legacy and Impreza engines. It makes 170 amps at idle and at least 160 amps hot at 200°F, which is far beyond a stock alternator and aimed at big audio systems, winches or accessory loads. It ships with an internal regulator and adapter harness, and carries a 2-year replacement warranty.

Questions and answers

Will this fit my Subaru without modification?
It is listed as a direct fit to OEM mounting for the Outback, Legacy and Impreza. Check your engine and year against the product code 11024-270-XP before ordering, since Subaru used different alternators across generations.
Do I need to upgrade the wiring?
Yes. A 270-amp alternator can overwhelm stock charge cables and fusing, so plan on a heavier gauge charge wire and an appropriately rated fuse. The 8mm x 1.25 copper output stud is the connection point.
How much power does it make at idle?
170 amps at idle, and 160 amps when hot at 200°F. That matters for systems that draw hard while the engine is idling, such as audio and lighting.
What is in the box?
The 270-amp alternator, an internal regulator and an adapter harness.
What warranty does it carry?
A 2-year standard replacement warranty from Nations Starter and Alternator.
Is it worth the investment?
If you need 270 amps and strong idle output for a Subaru, it is one of the few direct-fit options at that rating. For a stock car with no added electrical load, a standard replacement alternator costs far less and does the job.
Where is the 11024-270XP High Output Alternator for Subaru Outback, Legacy, Impreza cheapest?
At Nations Starter and Alternator, for $749.95, as of our latest check.
What do buyers say about the 11024-270XP High Output Alternator for Subaru Outback, Legacy, Impreza?
