Did you use the factory rubber grommet? I'm having hell of a time finding a grommet that fits.I have NO idea why the hell they essentially kept it in the stock location. The way I look at it is if ford wants to know what the charge temps are why wouldn't everyone else?
When I had an S trim years ago I put it just before the bend in the charge pipe going into the throttle body. Only thing I'd change is putting it on the bottom to make it a cleaner install.
