Alternator Denso or OEM Mazda

I went with Denso Reman for my choice. 2 years so far and no issue.

My auto shop is replacing the alternator on my 2013 Sienna for $657 with a DENSO part which is the only brand you should be using IMO.

Put the desno in fixed all my problems

Just bought one better denso at the auto parts store last year, was a 20min install, btw need to remove the rf tire and plastic to easily access as well as the bottom plates. Imo nice solid car and needs a decent part.

Denso is the OE for Land Rover.

Denso for sure, will last as long as the original, I think 20 years was a good life. The no name and parts store brand ones almost always fail shortly after install

With alternators and starters, only get Denso new or remanufactured if you can. The part store remans are junk.

I did the Alternator on my ES350 (same 2GRFE engine) and it sucked. It was my first major repair project and took almost all day for me.

The alternator (new OEM Denso, 2nd one, installed about 100kmi ago) on my wife's 2007 Solara v6 3MZFE with 227kmi just died last night. She didn't make it home.

I bought reman denso 2 years ago and it lasted 1 year.
