Alternator Denso or OEM Nissan

I would suggest Denso for the Honda. With a high amp usage like an Odyssey, anything, but Denso will cause the battery light to be on intermittently.

You can get a remanufactured Denso (OE) for that car: it's probably the most cost-effective option.

Nissan offered me around the same price for my 370z alternator replacement. I went to eBay and bout a used oem alternator from a rear ended total z with 3k miles on it for 80 bucks and changed it myself

I would get a better alternator. Denso (reman or new is fine) seems to be the only one that can take the high electrical demand of the Odyssey.

Denso alternators are the best. Denso makes great products. I do a lot of side work on Hondas and I am so thankful Denso offers their stuff outside of the dealership. I replace alternators, a/c compressors, oxygen sensors, etc all the time and I choose Denso bc it's basically the same exact part you receive in a Honda box but for half the price.

I replaced mine with a Nissan Quest alternator works pretty well and is cheaper with a higher current output there is a write up in the forums for it

If the alternator is OEM, replace it, because is close to the exhaust manifold, it will fail sooner than later.

If you are replacing the alternator, strongly recommend using only Honda dealer sold remanufactured alternators (probably Denso) or an aftermarket Denso brand remanufactured alternator. Lots of problems reported with other brands.

If you’re gonna go through the effort of replacing the alternator, do NOT get cheap shit. Get a new/remanufactured Denso alternator.

So I go to get some iced coffee because Dunkin just came out with pumpkin and the car doesn't start. Sputters. So I call roadside assistance for a jump. They tell me it can't be jumped and it's probably my starter. Real kicker is I then call for a tow, tow guy shows up and jumps it???? So I HESITANTLY drive it to the dealer who determines it's a bad alternator.
