Denso 210-0865 Reman Alternator vs NationsStarterAlternator 11024-270XP Alternator

The two listings are not interchangeable: the Denso 210-0865 is a remanufactured 150-amp unit for select Lexus IS, GS and RC models, while the Nations 11024-270XP is a new 270-amp high-output unit for Subaru Outback, Legacy and Impreza. Buy the Denso for a stock Lexus replacement where OE fit and a quiet, reliable charging system matter. Buy the Nations unit for a Subaru running big electrical loads, such as winches, audio or accessory lighting, and accept the higher output, billet pulley and 2-year warranty in exchange for a non-OE part. Owners of high-output alternators report strong idle output but more belt and electrical-system stress; OE-style remans are the safer choice for a daily driver.

  • Choose the Denso 210-0865 if you drive a listed Lexus IS, GS or RC and want a direct-fit, OE-configuration replacement with 150 amps and an internal fan.
  • Choose the Nations 11024-270XP if you drive a Subaru Outback, Legacy or Impreza and need far more charging capacity for accessories than the stock alternator provides.

What reviewers say

Denso 210-0865 Reman Alternator

Buyer feedback on this Denso reman unit is limited. Owners of the listed Lexus models generally report it charges correctly and fits as a direct replacement, while some note that reman units can vary in lifespan.

What people mention
  • FitmentMixedOwners say it fits the listed Lexus IS, RC and GS cars directly, but the Subaru name on the listing causes confusion.
  • Charging outputPraisedBuyers report it restores full charging and clears battery warning lights.
  • Reman qualityCriticisedSome owners say remanufactured alternators can fail sooner than new OE units.
  • ValuePraisedBuyers see it as a cheaper way to get Denso OE-style charging than a new alternator.

Questions and answers

Will the Denso 210-0865 fit a 2022 Subaru Outback 2.4L Turbo?
No. The Denso listing covers select Lexus IS, GS and RC models, not the Outback. For a Subaru, the Nations 11024-270XP is the matching part in this pair.
Is the Nations alternator a direct replacement for a stock Subaru alternator?
It mounts to the OEM mounting points and includes an internal regulator and adapter harness. Output is much higher than stock, so check belt condition and wiring before installing.
Which lasts longer?
The Nations unit is new with oversized bearings and a 2-year warranty. The Denso is remanufactured but built to OE specification. Longevity depends more on load and installation than on the label.
Do I need 270 amps on a daily driver?
No. A stock Subaru is fine with stock output. The extra capacity matters for winches, large audio systems, lighting or dual batteries.
Is the Denso worth choosing over a new aftermarket alternator?
For a listed Lexus, yes, if you want OE fit and regulation. It is the safer choice for sensitive electronics and a stock charging system.
