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

Delivered as promised, priced right. No more hesitation starting up right away. Better fuel mileage and more responsive on the throttle. Check engine light is off and has been off since replacing I am very satisfied.
