The positive aspects of the NGK Iridium vs Bosch Iridium 4s was never addressed in the plug thread from over 1 yr ago.

The only response was "try them and you won't go back".

Ran the NGKs in my E46 330i perf pkg 6 spd, didn't notice any improvement.

I believe in deadication to craftmanship in a world of mediocrity!
