Rating: (see review/s)

"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
