I was under the hood changing the air filter so i thought I would check the intake bolt torque after a week of driving. Sure enough they were almost a half turn loose again so I retorqued them to 90 in/lbs. From what I have read the bolts are not really loosening off. Several guys on a Challenger forum have torqued them, driven it for a month and retorqued them, then marked them. After driving for months and rechecking the marks, none moved. I think if you keep torquing them down eventually you will mash the intake seals and/or crack your intake. I think I will leave mine alone now since they have been done twice.
