I would not put anything but NGKs in. You change plugs every 4-5 years if that and the idea of saving 40 bucks on 6 of them isn't worth it. Bosch generally makes good stuff but when it comes to spark plugs NGK is da man!

"wrong plugs" are you serious? Go ahead and put those 40$ plugs in there.

I offered my two cents worth. I'll do what I do you can all do what you do.

I'll back you up that the plugs you used aren't "wrong". There is a specific Bosch p/n at 2+ bucks for this engine. However laws of physical aside I noticed that some plugs are more prone to changing the gap over time. Gap is key to good timed ignition. NGKs in my experience have been a lot better at maintaining the proper gap over longer periods of time.

The NGK 2667's are the Iridium verision NGK's. Did you notice any difference with them? I have been curious to try these on my 2000 328Ci.

yes i have seen an improvement in power and gas mileage.. the last time i changed plugs were about 30k miles or less and they were ngk bkr6equp, the point for the 2667s is its a colder plug and you will thus see an improvement in gas mileage and power ironically... i get much better pulls from 60-90... the only problem i saw was i did the intake manifold gaskets a couple days later and now with the changes in spark and all the computer cannot adapt via o2 values its reading so i need to go in for a SW update on my DME... it was in a service bulletin but im out of warranty and i cant stand a ses light... i def would recommend the colder ngk 2667s

jackeatsemokids recommended them for m54s

oh and i drive a e39 530i but same m54 as the 330i
