I received my order from the dealer. The plugs they sent are p/n 999.170.183.90 Beru Ultra R6 219. They are the tri-electrode but when reading past threads, many people spec'd FR 5DTC. What are your thoughts on these plugs?

Should I return them and specify the latter?

thanks for your input!

Chris,
The beru is ok. FR5 DTC is a Bosch plug.

sorry to bring this up again, but I am getting ready to change the plugs and want to be sure I'm installing the correct one's.

I see stamped on the steel part (below the hex)
FR 5 DTU

is this a sperceded p/n to FR 5 DTC?

thanks in advance!!!!

I forgot to mention I presume '5' is the heat range. the DTU suffix means? I am curious the difference between the specified DTC vs. the DTU that was sent to me?
