Will this fit my 2003 Honda Accord?

Yes. The Remy 12463 is listed for the 2003 Honda Accord with 105 amps. Check your engine and original amperage before ordering, since trims can differ.

Is it new or remanufactured?

Remy sells both new and remanufactured alternators under the same part numbers. Confirm the condition with the seller before buying, since the price may reflect a reman unit.

How hard is the install?

On a 2003 Accord the alternator is accessible from the top with the belt removed. A DIYer with basic tools can do it in about an hour; a shop will charge a few hours of labor.

What else should I replace at the same time?

Inspect the serpentine belt and tensioner while the alternator is out, and check the battery. A worn belt or weak battery can mimic alternator failure.

Is this a good value?

It is the lowest of the six new prices tracked as of November 8, 2026. Dealer alternators for this car typically run several times that, so it is a good budget choice.
