page305 Posted April 12, 2010 Report Share Posted April 12, 2010 I just had to replace a coil in my SS, the mechanic told me that the E3 plugs are what did it... Does this sound right to everybody? I really don't want to change them out if it's not true... he said they're too high performance for the stockers... Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted April 12, 2010 Report Share Posted April 12, 2010 It isn't that they are too high performance, they just suck LOL. Our trucks do not like these plugs, it is best to stick with an NGK or AC Delco plug. There have been several other people that have had running problems due to these plugs.......
