Needed new plugs for my 4.0 liter jeep grand cherokee 99. Got a set of these at NAPA and installed em without too much of a problem.
Just a little anti sieze and in they went. No problems running on them for over 4 months and am happy with them.
Maybe the iridium, vandium, laval hot uranium delpeted plugs are cooler ; but these Truck Plugs do the work so just enjoy em after the install --
