gmc55 Posted December 30, 2006 Report Share Posted December 30, 2006 I have 82,000 miles on my truck and haven't changed my plugs and wires yet. I know it wouldn't hurt but should i do it now and will i be able to tell a difference in mpg and performance? Quote Link to comment Share on other sites More sharing options...
