Rating: (see review/s)

"This spark plug is the only plug my 2007 Charger 3.5 will accept. Tried other plugs, car misfired each time. Plugs that have to be "gap checked" do not fare well in the SXT model. These are less expnsive, but so what.. I change them every 25,000 miles anyway. It is a matter of preference, and I love preventative maintenance. Again.. you will do alright by these plugs." posted by: Commander on December 25, 2009

"Great plugs. Grab em and get new wires while you are at it. I noticed a slight increase in gas mileage on my gas hog 01 Ram 5.2L. Engine runs smoother with no missing like it did with old AC Delco gapped plugs." posted by: Motorhead5 on September 28, 2013

"These plugs were 100K replacements and resulted in instant smoothing of idle faster initial start up and overall should result in improved fuel economy. Overall acceleration was also improved." posted by: Dave on September 17, 2013 view all 2 reviews
