Am replacing the spark plugs in my 1999 540i with the original-type NGKs listed in my owner's manual. Torque on spark plugs in aluminum heads is always important, but I cannot find that figure anywhere in my owner's manual. Does BMW think ALL of its owners would be helplessly dealer-dependent?!?

used Even my Honda's owners manuals specified spark plug torque!
Anyone know the required torque for spark plugs in a 1999 540i? Please help, thanks!
