Where's the torque??

I got BPR6ES (one heat range colder) at napa for $2 a peice over the counter, so they should have them in stock almost everywhere.

Bosch plugs are OK but I made the switch and I don't think I'll be going back. :)

Ok I'll look for those and try them out. What difference would it make or would I feel (if any) by swapping out just the plugs? Or is it a matter of prolonging engine life?

platinum plugs don't seem to work well in older BMW engines. Platinum is great marketing tool (along with all the other BS, like split fire, multiple tips, etc. etc.) and they're meant to be less maintenance intensive, but I've never found any real benefits. In fact they've typically made the engines I've tried them in run worse, and they cost a lot more to boot.
