After several hours to install and using these plugs I am sorry I tried them the vehicle lugs under load and the gas mileage dropped 5 miles per gallon and you know this 4.2 liter ford does not get good mileage in the first place.. DO NOT WASTE YOUR TIME AND MONEY.. THEY WILL CHANGED SOON. i DID GIVE THEM A CHANCE SEVERAL THOUSAND MILES OF DIFFERING DRIVING.. USELESS
