Alternator OEM Toyota or Bosch

I just replaced the one in my daughter's Mk 4 with a rebuilt 120A Bosch one from Rock Auto last week.

I would go Bosch if I had the option. Mine went out on a road trip. I had to go with what option was available at the auto store I was able to limp to. Lucky there was one close by but it was who knows what brand. It was my only option so I bought it. Probably duralast or something but it’s working 2 years later.

I had a car get flooded for 6 months and the Bosh alternator still worked perfectly for another 21 years. Would buy again

Fcp euro has an 100amp bosch one that works well. They have a lifetime warranty too.

Funny enough, I just did this dance today! Found a nearly new looking Bosch unit that someone had already kindly removed from the wrecker's car for me. Got it installed and tested exactly like yours though, so I'm happy.

I have a 96 that I purchased with 40,000 miles and am just shy of 300,000. Most reliable car I've ever owned. Biggest "issue" I've had was replacing the alternator besides normal maintenance.

The alternator went out on it, and I had to replace it four times due to faulty over the counter rebuilt Bosch parts.

I just went through a headache replacing my 3rd alternator in 2 years. I took it to the shop and they put an oem alternator in it and told me not to buy the parts store alternators. It's fine if you don't mind pulling them out to replace every year or so.

My worst breakdown? A 2003 Toyota Tundra I had died on the highway from a bad alternator and I was able to pull over to the shoulder.

7 alternators in a row. Wouldnt charge. Or only charged for like a minute.
