Plain and simply, not a huge difference. However, the acceleration is noticeably quicker and smoother. Before installation it felt sluggish and hesitated from a stopped position. The hesitation and sluggishness is gone. In not way would I say 'wow', but there is a difference and you notice it. Took a little longer as I was meticulous, but it was 3 plugs in the engine, and one on the gas pedal. Spent 45 minutes doing it with a 2 and 4 year old 'helping'. 10 min max if done again.
