""I installed these on my 2012 Cheverolet truck with the 5.3 liter engine that has 8600 miles on it. I sent Granatelli a email to get the correct set. They are a little long but work fine. I saw improvement in performance after installing them but more improvement after disconnecting truck battery for a hour to clear computer memory. The truck runs much smoother with more power, does not down shift as much. I have only drove about two hundred miles on new wires so can't say for sure about gas mileage although based off truck computer fuel caculator it seems to have improved around 10%. I am hoping for more with more driving. Over all I am very happy""
Pros: Improved performance
Cons: A little long for application
