Will this fit my 2012 Acura MDX?

It is listed for MDX models from 2010 through 2013. Confirm your original alternator's part number matches 11391 or one of the listed cross-references before ordering.

Is this a new or remanufactured alternator?

It is sold as a new replacement alternator, not a rebuilt unit. The listing includes one alternator.

What output does it produce?

It is rated at 12V and 130A with a 6-groove pulley, matching the stock rating for these Acura models.

Does it come with a warranty?

Warranty terms are set by the seller, so check them before buying. There is no widely known reliability record for this brand.

Can I install it myself?

It is a direct-fit replacement, but alternator swaps on these V6 engines take time and basic tools. A shop is safer if you are not experienced.

Our take on the SINOCMP 11391 Alternator for Acura MDX 2010-2013

The SINOCMP 11391 is a 12V, 130A replacement alternator with a 6-groove pulley, built to fit several Honda-built Acura models from roughly 2009 to 2014. It cross-references OEM numbers 11391, 290-5222B, AND0484, 400-52269R and 400-52523, so it can stand in for the original Denso-style unit. It suits owners of an MDX, TL, TSX, RL or ZDX facing a failed alternator who want a direct-fit part rather than a rebuild. The main trade-off against a dealer part is unknown long-term durability and no established reputation, so the warranty terms matter more than with a name brand.

Best forAcura MDX, TL, TSX, RL and ZDX owners replacing a failed alternatorDrivers who want a direct-fit 130A unit with matching OEM cross-referencesOwners doing their own repair who can verify the part number before ordering

Pros

130A output matches the original equipment rating for these models
6-groove pulley and front-mounted layout match the factory fitment
Cross-references several OEM and Lester numbers, making it easy to confirm the match
Aluminum housing keeps weight around 5.5 kg, close to the stock unit
Sold as a complete alternator, ready to bolt on

Cons

No track record for longevity compared with Denso or a dealer part
Warranty and support depend on the seller, not a national brand
Fitment spans several models and years, so the wrong variant is possible if you don't check the number
Remanufactured or OEM units are often the safer choice for a daily driver
