Stay Away From These Spark Plugs!

I got these "OEM BOSCH" spark plugs as the first step in trouble shooting a constant rough idle without any codes. I replaced injectors, VCG (thinking spark plugs were getting covered in oil), cleaned valves and replaced several vaccum lines,

TURNS OUT! these amazon bosch spark plugs are NOT real BMW BOSCH certified replacements. They seem to be a leftover defective batch. That is why the price is so low. Stay away from them! This is the link:

Don't spend over $1000 changing stuff like I did before you notice your plugs are poo.

I bought those back in Feb of this year and replaced all six. I haven't had any issues with them. I've had to replace a coil pack recently, but since 3 others failed right before i replaced the plugs, im assuming they were already on the way out.

where did you find out they were not real Bosch replacements?

Looking forward to finding out the details on how exactly you blew the lid off this scandal.

Same here, on Feb 6th, but they were being sold by and shipped from "Mueller Motorwerks" at the time, and not this "partzhub" seller. Part #s matched OEM and they looked perfect before I installed them. My "Orders" page now links back to the same company as OP's though. Interesting, though I haven't had any issues with any of mine as of yet (2k miles later). Something to keep an eye on I suppose.

I do see quite a few one star reviews on those the last couple months recently, but I'm guessing they're just a defective batch of Bosch plugs. I mean, who the hell would counterfeit a plug for so little profit? The MaxPayne reviewer on there who took pics of 2 different types of box didn't realize the bar codes are identical, just closer together on 1 box than the other, though the washed-out graphics comparing the boxes might be a legit concern.

EDIT: Apparently there's enough money in fake plugs to warrant Denso creating this doc on their own site:
http://www.globaldenso.com/en/produc...a/pdf/P043.pdf

Guess I'll inspect mine the next time I have a chance to check burn pattern and for damage. Odd...

This is why I don't buy parts I'm relying on to keep my car running from Amazon or EBay. Not to say that there aren't reputable and legit sellers out there but there's also a higher risk for something like this to happen as opposed to ordering from well established companies that specialize in selling quality parts. Don't get me wrong, I use Amazon and Ebay to purchase tons of stuff, but if prices are suspiciously low chances are there's a reason.

You know there are multiple sellers on Amazon, right? I would dispute with whomever you bought them from and try to get a refund.

I totally understand the sellers vary but whoever is working with Amazon prime is scamming people. The sparkplugs where visually very different and inconsistent (gaps fluctuating from plug to plug) and the car ran poorly from day 1. Meaning all cylinders were runnings rough. What are the chances of getting 2 or more defective spark plugs out of 6? Pretty slim.

I think there is just something fishy about them. I know a lot of you all have used the. Successfully. A lot of 5 star reviews on Amazon too. But also tons of 1 star ones.

I agree. You definitely got a bad batch, or a bad seller, or a bad something. I checked gap and condition on all mine before install and they were perfect so luckily I must've received a good set (now watch...). Again though, different seller name on mine compared to the page that loads now. Who knows. Hopefully you can get your money back.

Yes! They probably needed replacing due to rough cold starts anyways, but the rough idling and poor mpg was never due to injectors.

That is good to hear.

Could you update the other injector threads with your resolution.
