Default Replaced Spark Plugs - NGK G-Power

The G-Power seemed to be one of the recommendations for the V6. I did a search on
G-Power plugs, and got some videos recommending them for the Mustang 4.0, so I
picked up a set.

Mine came out relatively easy, nothing broke, and they were pretty bad:

Every plug looked about the same or worse, and they all smelled like fuel.

Started up much quicker, and smoothed out the idle. I have been getting about 25MPG, so will run this
Sunday and see what it gets.
