smokey1369 Posted April 27, 2008 Report Share Posted April 27, 2008 has any one used E3 Spark Plug in ur SS ?do they work? Quote Link to comment Share on other sites More sharing options...
packjh Posted April 27, 2008 Report Share Posted April 27, 2008 if you do a search on here they have bad reviews and i dont even think they sale them for the 6.0l....they suggest the 5.3l atleast last time i was looking at spark plugs they did. I have a few buddies that said they suck as well, said their truck ran crappy after installing them. Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted April 27, 2008 Report Share Posted April 27, 2008 (edited) Save your money, those plugs are expensive plus they are not all they are cracked up to be.....NGK TR55's or NGK TR55ix(iridium tipped) work great on our trucks.

Bonj87 Posted April 27, 2008 Report Share Posted April 27, 2008 ive been running them for the past year. i can tell you i have not seen a drop in performance. in fact, on a flat highway, set at 55 or 65 mph on cruise, i can hit 21 mpg. i didnt see a drop in performance from my seat of the pants point of view. i am about to change plugs soon, i may go back to the NGK's, and see if my MPG's or performance changes. but I have nothing bad to say about the E3's Quote Link to comment Share on other sites More sharing options...
12'SROCK Posted April 28, 2008 Report Share Posted April 28, 2008 you should only run AC Delco plugs or NGKs on GM vehicles Quote Link to comment Share on other sites More sharing options...
NTMD8R_SS Posted April 28, 2008 Report Share Posted April 28, 2008 Not worth the $ IMO. Quote Link to comment Share on other sites More sharing options...
