These are a must have Cheap Upgrade!
Just changed the stock sparkplugs in my 2014 Focus ST with these and what a difference. You can just click the start button and the car immediately starts, touch the gas pedal and the engine roars. There is no lag anymore, the throttle responds near instantaneously.
