I'll dogpile on too...I don't recall if it was there way back when I first changed my spark plugs, but I've never put any on. Out of curiosity I looked in the service manual and it does specify Loctite on the ignition coil bolts (though it didn't say what specific kind), along with 7.2 ft/lbs of torque. I've never used a torque wrench in that particular area either. With torque values that low, I tend to trust my wrist more than I do my Pittsburgh torque wrench.
