Plugs replace OEM and now trouble free by optyman, January 8, 2014

Had trouble with engine missing. Not certain if problem was related to bad gas bad coil (no codes) or bad spark plugs. If you are changing coils you might as well change the plugs too. Sprayed electrical silicone on threads prior to install to aid in installation on an E350 V10 Ford Engine with plugs hard to get to. Also replaced the PCV valve & fuel filter and added Sea Foam to the gas tank. Saved hundreds of dollars for a tune-up as the 2000 Van runs great now even in the cold!

These plugs have a great feature as they are gap less, just take them out of the box and install. Cuts down on time and issues of a wrong gap. These plugs have made my car run great and now gets better fuel mileage.
