Best plugs i have ever bought. I can feel the boost immediately. Will never need to buy a different brand. Very pleased.

They perform perfectly in my daily driver, most notably a slight hesitation that my truck has always had is gone. I haven't noticed a big difference in fuel economy probably due more to the winter blend fuel! COME ON SUMMER!
