Carl Buyer Posted June 2, 2016 Report Share Posted June 2, 2016 Embarrassed but amazed, that I drove 220K miles on the original set of spark plugs. I have attached a picture of one of the 6, but they all looked identical. Maybe with electronic control systems this is expected, but the gap being over twice recommendation, and only about 10% of the electrode, let alone they were pointed (picture attached is of one of the 6, the other 5 looked identical). Gap on the original plugs was average 0.110. The vehicle ran okay, 21.4 mpg, I am hoping to see some improvement with the new plugs (also change the rear injectors, although they were replaced at 80K, only 140K on them. The front injectors have 220K). I have put around 500 miles on the truck since the change, and I definitely feel improved performance. Torque and Fillup (android apps) are showing some improvement on mpg, but will not pass judgement until at least I run through two full tanks. Interested in feedback, is this out of the ordinary, as I have heard that new systems with high quality plugs can go 100K? 1 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted June 2, 2016 Report Share Posted June 2, 2016 Mostly highway driving? Hard to believe if mostly city/stopngo driving. Gap growth does sound about right though. You changed the rear injectors again? There are always "oddities" and your Edge could be one of them And, welcome to the forum! Quote Link to comment Share on other sites More sharing options...
