Swapped out the old NGKs on the bimmer, and replaced with new Bosch FGR7DQP.

Anyone see anything I should be worried about? If I'm reading them correctly, they all appear to indicate I'm running lean. Which might line up with the codes I pulled. (P0171 P0174)

Next job is to check the MAF and clean/replace as necessary.

The car in question is a 2002 BMW 330i with 127k miles.
