Title: Good plugs. Noticeable improvement in starting and pep.
Review: Installed these plugs on a Toyota Tundra v6 model. The truck was sluggish and gulping fuel. I installed these plugs, some new wires, a new fuel filter, and new oxygen sensors. The improvements in idling, acceleration, fuel consumption, etc... were impressive.The truck runs good. Tune ups are important.Great iridium spark plugs. Price is reasonable for what you get.
