I know a large part of that, probably 1-2mpg's, was from the wind, but still I am pretty happy about it!

Don't use this.....
Use techron instead....
At the dealership our plug changes got more successful with customers using the techron in TWO tanks of gas before their plug change than using seafoam.....

Crack the plugs 1/8 turn and soak with carb cleaner for an hour....

then use an Impact and have the lisle tool handy.....

Coat the nose/ heat shield only with the nickel anti sieze and not the threads.....
