NGK Iridium spark plugs help restore throttle response and gas mileage in Dodge Dart with 2.0/2.4L engines

Looking to get back some of the crisp throttle response your Dodge Dart / Jeep Renegade / Jeep Compass / Jeep Cherokee / Fiat 500X /2015-2016 Chrysler 200 / or Ram Promaster with 2.4 liter engine had?

We tested out a set of these new NGK iridium spark plugs in our 2014 Dodge Dart with 2.4 engine and were impressed with the improved throttle response afterwards.
