You have to get either a wrench or I think snap on makes a special tool for it. I took a 10mm wrench and heated it with a torch and bent it, after bending you have to use the wrench to hold the nut down. Then when your holding it you can use the screw to tighten and loosen the screw as needed. If the intake specs are .007-.008 make sure to tighten it down using the .007, it takes a lot of practice but you have to get it just right so the .008 wont fit, and the .007 will. Have fun. I'll take a pic of my wrench I made when I get home.
