Hi, I am a new DIYer and went to change my plugs in a 2005 Accord V6. Most people I asked for a torque wrench told me not necessary and so I went to do it by hand lightly. The car idled roughly and when I went to check on the plugs they were pretty loose, a HAIR past hand tightened. Definitely looser than my hand tighten and then 1/8 to 1/4 turn.
So I tightened them, all but the back right one. Now, afraid that I’ve over tightened them, I would like to ask what is a good torque wrench for spark plugs? I can’t find one good for 13 lbs, also, now that I’ve definitely crushed the steel washer on the NGK iridium plugs OEM to my car, how much torque do you think that might be? 16/17 lbs now needed?
Thanks and I’m sorry if this is repetitive. It’s surprising how hard it is to find a decent torque wrench for this.
