Yes, appeared to be Bosch from packaging and logo, etc.

1) I weighed them to the nearest gram. They were 25 grams lighter than stock Bosch that came installed from factory. I am original owner so I know my originals were legit.

2) The packaging had serial numbers which I did check on the Bosch website, and they could not verify they were original.

3) They had an odd smell, almost like they were burned.

4) The packaging just seemed off. Like used somehow.

5) I had misfire codes on every cylinder in under 10 miles. I am tuned, so I’m guessing these coils might work ok on a completely stock engine. Tuning software reads codes (MHD).

Eldor coils COMPLETELY solved my issue, not a single misfire since. Spark plugs seem to be fine. Eldor coils also from FCP and weigh more than even the stock Bosch genuine coils. Better part.

I’m guessing FCP didn't realize these coils were fake. Their supplier perhaps sold them as real and they were intricate fakes. But I have no doubt they were fake.
