Trouble loosening the old spark plugs
I have a 2008 335xi AT, 30000 miles, Running Cobb Accessport Stage 1+ with FMIC and DCI.*I followed Cobb's instructions to change the spark plugs and stopped when I could not remove spark plug #1. I applied about doubled the amount of torque (45 nM) for loosening than is required for tightening (23 nM) and then stopped in fear of breaking the spark plug. Suggestions?
