The NGK Ruthenium 95605 are, in our opinion, the best spark plug upgrade for your 3.5L EcoBoost Twin Turbo V6. We typically gap them to 0.028" which is 0.002" tighter then out of the box, but have the option to go to .026" for those of you running Ethanol based fuels! These -1 step colder spark plugs provide unparalleled durability and a more complete fuel burn resulting in a quicker throttle response, smoother idle and better cold starts.
