I think much of what you THINK you notice is what I call "confirmation bias", or a simple psychosomatic response. You expect to feel a difference (you even WANT to feel a difference) and so you feel a difference.
Blindfold you and don't tell you what tires are on (or which quality-brand spark plugs are in the motor) and you won't feel the difference any longer.
