Or the way a cheap skate like me would do it; pull them, rinse the tips in acetone, gap them, and put them back.

wat? How can you tell me that 150lbs*3 = 6hp? Further more he says 3 passengers, and I don't know if that's including himself but if it isn't, then it's 600lbs! 600lbs or even 300lbs is a big deal in a car and should have a far larger effect than only 6hp!
