Hello, It looks like the air intake assy needs to come off to access the distributor cap on my 5.7. I loosened the plastic wing nut, but the air box wont budge. It looks like it's been glued to the throttle body with silicone. I don't want to use a pry bar and wind up breaking something. Any help concerning removing air box and proper procedure for replacing distributor cap and rotor would be greatly appreciated!
