May 6, 2010Hey guys and gals! I recently bought a superchips flashpaq $365.00, i also put E3 spark plugs from summit, and have gibson headers with magnaflow exhuast, i also only use Royal Purple Oil and K&N Oil filter! Now i dont know about anyone else but i recently did a MPG test and found that before i added all these parts i wasnt able to get better mpg than 16, Now at 55mph i am getting 24mpg and on the highway at 69mph i am getting consistantly 20mpg! I highly recommend that you try these products, all i can say is to me this has been a good investment! U make ur own choices! Has anyone else put any of these on your trucks and how do u like them?
May 9, 2010Can`t remember which engine, but other members haven`t had good luck with E3 plugs. If you see them go downhill, maybe try Autolites.
May 10, 201028 mpg? BS!
Is this what your overhead console says? or did you actually do the math with the miles divided by gallons and what not?
September 6, 2010as far as the e3 plugs, get rid of them, the 4.7 likes the autolite 3923 plug, they are a cooler plug, i run the autolite 3922 plugs because i constantly push 125 shot of nitrous thru my 05 4.7, on a good day i can get about 22 on the highway cruising at 65, with 4.10 gears, around town i would be lucky to get 16 with stop and go traffic. i run the sct tuner fron what use to be krc performance, but Mr. Powell is one hell of a tuner
That right i did it, cry to tears in a bucket, **** it, lets take it to the stage
September 12, 2010Sounds unbelievable but awesome if its true
December 16, 2010E3s arent worth the money at all
May 6, 2011Thanks for the comments I just might go get those autolite plugs they sound like a good plug thanks, and yes I edited the original post since after I did the math my results changed a little!!! But that`s ok since that`s what life is about. The ability to change and adaptation is the key and always being able to take advise not just giving it!!!
May 6, 2011I ran a 4.7 in my Dakota Quad Cab for years, and the best plugs I found was the autolites... now, in my HEMI, I have no idea what they have, cause i havent changed em yet..
May 16, 2011Well if u see this it means I dumped those E3 plugs due to the 4.7 hates them plugs, oh well!!! I am still getting great mpg with these Autolites so far I ran them all week and still getting 21-23 mpg depending on the wind and rain.....on good day I can get 24 at 54 mph with cruise on. 21 on highway at 68mph with cruise on just gotta watch the hills
